Equipment for ball joint repair: prerequisites for use, subtleties of operation and popular models


Recommended Posts

Equipment for ball joint repair is very popular today. Why? I propose to sort this out together.

The quality of roads, unfortunately, is far from always meeting the standards that we would like to see. This is well known not only to all drivers, but also to passengers. The first thing that suffers from this is the ball joints, which during the movement of the vehicle experience destructive effects from all sides. In the picture, the zones of maximum load exerted on the nodal connection are marked in red:

The node itself consists of two elements:

  • Sleeve;
  • Swivel ball.

Between them is a special polymer, which:

  1. It softens the force of ball impact on the sleeve;
  2. Minimizes the effect of friction of metal parts against each other.

All problems, including wrest the wheel on its side, are possible if the polymer liner is worn, which is inevitable over time.

SJR technology avoids such a catastrophic outcome and, with timely intervention, maintains the performance of the ball joint almost endlessly. How it works? Let’s figure it out.

SJR Technology

There are two methods for ball support recovery using SJR equipment:

1.Indiscriminately

Equipment for ball joint repair: removal of old polymer Removal of old polymer
  1. Drill a hole in the case of the sleeve;
  2. Burn the remains of the old polymer with a gas burner;
  3. In the extruder, melt a new batch of polymer
  4. Under high pressure, the molten polymer is injected into the cavity between the ball and the sleeve through a hole previously made.
  5. The solution fills all the voids, solidifies and forms a new liner, not inferior in its characteristics to the factory insert.

2. Demountable

The collapsible method is more complicated and longer, but also more efficient. It is used when there is significant wear on the ball joint, the appearance of rust on the ball.

In this case, the repair begins with the following steps:

  1. Cut the sleeve in half.
  2. Polish the ball.
  3. Brew sleeve.

The final steps are the same as in the previous method.

Benefits

The advantages of using this technology are quite obvious. It:

  • Economic benefit. Recovery is always cheaper than buying a new part;
  • Universality. Suitable for the restoration of any ball joints and steering tips;
  • The compact dimensions of the necessary equipment. Even the largest machine can easily be rearranged from one place to another by one person and can be comfortably located not only in a spacious car service, but also in a small garage workshop;
  • Cheap consumables.

Variants of suitable equipment

The operations described above can be carried out using various equipment that differs from each other:

  • At the cost of;
  • In size;
  • Power;
  • In level of automation.

We will briefly consider four models presented on our website.

Equipment for ball joint repair – Light version

Equipment for ball joint repair - Light version

The simplest version of equipment for recovery of ball joints and steering includes:

  • An extruder for heating and forming a polymer consistency;
  • Three interchangeable adapter fittings, with which the solution is charged under pressure into the problem area;
  • Remote thermometer that allows you to monitor the temperature of the detail at a distance;
  • Five polymer rods, shipping container and instructions.

The pressure of such a device is only 25 kg / cm2 , and it needs a compressor with a capacity of 7-10 atm at the service station. The set is quite economical in terms of financial expenses, as it costs only 180 $, and is compact, but quite demanding on additional equipment and labor costs from the operator.

In the next modification, the piston power reaches 100 kg / cm2 . But its main advantage is the presence of a high-quality mechanism for centering the ball joint. Such an addition allows during the introduction of the molten polymer to firmly and reliably fix the part in one position. This facilitates the work of the operator, and the quality of the result improves.

The cost of such equipment reaches 640 $.

Equipment for ball joint repair – SJR 3 machine

The SJR 3 machine will cost 1 180 $ for your workshop, but will eventually work out every cent invested and will bring considerable profit from above. This is a fully automated unit, equipped with all technological advances.

Here are just a few of its most significant advantages:

  • The created pressure – 240 kg / cm 2 ;
  • Full control of the melting process;
  • Automatic nozzle feed;
  • Mechanical clamp and centering of the ball joint;
  • Robust cast housing.

Conclusion

The restoration of ball joints and steering tips using SJR technology is a technologically advanced, profitable and easily feasible process in the presence of the necessary equipment. It is noteworthy that such equipment is available in different price categories, so that every car repair shop can make the optimal choice for itself.

      Hey, everyone, I will explain some advantages of PDR over traditional dent repair. I think it will be helpful for you. 
      PDR is the process of restoring the dented or damaged panels of your vehicle’s body back to the factory finish. This is done by reshaping the sheet metal back to its factory-designed shape without causing any damage to the original paint.
      PDR tools/dent tools such as Led reflection light are used to help the technician see even the finest details of damage that has occurred to the body; along with any imperfections on the painted surface and the Orange Peel – texture on the painted surface of a vehicle.
      For technicians performing PDR, being able to identify their tooling through the metal panel is essential. Specialized PDR lights cast a specific light contrast onto the panel of the vehicle; creating dark and bright spots that amplify the texture. Think of this process like using a zoom or magnification feature so that every tiny detail and imperfection on the body is easily identifiable.
      With proper lighting, the technician can see through the panel and make the right pushes to restore the panel back to its original position. Moreover, it ensures that the repair is completed to the highest level of perfection and as if no damage ever occurred to the area. 
      Trained technicians use the PDR technique to remove small dents and dings from vehicle bodies with ease, as it helps avoid repainting the affected parts. It allows vehicle owners to elude expensive repairs such as replacing vehicle panels or even repainting the whole vehicle to match the repaired part. However, sharper dents may still require traditional auto body repair.
      On the other hand, traditional auto body repair typically involves welding steel pins into the sheet metal and filling in the gaps with fillers (plastic or glass). Conventional repair, more often than not, requires spraying tons of layers of harmful chemicals, in efforts to bring the sheet metal closest to its factory-set shape, as you wait for weeks with your vehicle parked at the workshop.

      Bad shock absorbers – dangerous driving. The vehicle is due to their failure poorly manageable, the wheels have little traction with the road surface. This also leads to a malfunction of the brake system. The main task, which is carried out shock absorber in car, is to control and hold the wheel while driving. This avoids losing control of the vehicle.
      Shock absorbers are also designed to damp vibrations that occur when driving on an uneven surface, off-road and when the speed changes. Springs do not always cope with the load. Consequently, the safety of the vehicle and passengers directly depends on the shock absorber. Therefore, it is necessary to pay special attention to the selection of these parts of the chassis of the car.
      The structure and types of shock absorbers
      Shock absorbers consist of a cylinder with a piston inside and a valve mechanism. The combination of such elements in this system allows you to damp the vibrations in a timely manner and prevent the car from swaying violently.
      Varieties by the principle of action
      The most common are hydraulic and gas shock absorbers:
      Hydraulic shock absorbers put out the vibrations of the elastic elements of the suspension using oil that flows from one tank to another through a valve system. Gas shock absorbers they also use liquid, but it is preliminarily “squeezed” by a small volume of gas. Varieties in structure
      Two-pipe . Single-tube with gas pressure. Two-pipe with gas pressure. Single-tube have advantages, because the liquid in this device does not overheat. They are also practical: the housing can be installed up and down.
      Two-pipe ones consist of two cavities, one has a piston with valves, and the second is necessary to partially fill it with oil and air. If they are absent or too few in design, then the shock absorber stops working or is compressed without resistance. In the event of such malfunctions, it is necessary to contact a car service or service station that has equipment for repairing shock absorbers. This device will restore the performance of parts.
      Diagnostics of malfunctions of shock absorbers and the main causes of their failure
      Checking the fault is quite simple:
      If during driving the car does not shake and extraneous noise is not heard, then the shock absorbers function normally. If in motion there are problems with braking, smooth running, fitting into a turn, and also the car cannot gain a certain speed, then it is necessary to pay attention to the condition of the shock absorbers. Such problems can lead to an accident caused by an increase in wheel slip vibration. Most often, the main cause of the breakdown may be leakage of fluid through a damaged seal. This can happen in such cases:
      Wear of the sealing material due to friction. Sudden change in temperature. Dirt and dust are trapped in the shock absorber. Gas or air are trapped in the shock absorber. To avoid breakdowns, it is necessary to seek the help of professionals in a timely manner, who will make a diagnosis and restore the parts if necessary. This can help special nozzles that are used to repair gas-oil shock absorber. They allow you to pumping gas, add fluid, and also control the pressure process.
      Equipment for repairing shock absorbers is a special device that will allow specialists to restore the main part of the suspension quickly and efficiently. In total
      The oil and gas parts of the undercarriage are important elements in the design of the car. They are responsible for its performance, safety during movement. Today, A-PROFI Company provides an opportunity to protect yourself and your car by manufacturing quality restoration equipment that meets all the requirements of modern automotive industry. You can study or buy equipment for the restoration of shock absorbers on our website.

      Technics process also consists of one or several tactic processes, one process consists of several steps.
      A process is an elementary unit for types of equipment production technics process.
      Process definition
      Process definition is the technics process, that one worker (several workers) finish production continuously on one machine (or one position) for the same workpiece (or several workpieces).
      The main characteristic of the process is that it doesn’t change the workpiece, types of equipment, or operator, and continuously.
      The step is based on the same CNC lathe machining surface, the same CNC lathe machining tools and the same volume of feed
      The Feed is a working process, which is a step for production finish on the workpiece’s surface by tools.
      Technics flow
      When making the types of equipment’s technics process, you have to make sure how many steps the workpiece needs and the sequence.
      Technics flow is a simple process of key processes and sequences.
      Technics flow is very important for making technics process,
      Its function is to select the correct processing method for each surface, make sure the sequence of each surface, and the number of processes.
      (ii) Productive Category
      Productive Categories are usually divided into three categories,
      a. Single workpiece production:
      Manufacture different structures’ and dimensions’ workpiece separately, and seldom repeat. b. Batch production:
      Manufacture the same structure and dimensions’ workpiece among one year, there is some repeatability in the manufacturing process. c. Mass production:
      The quantity is huge, manufacture the same process in the same place. (iii) Process planning
      Planning principle
      1. Every technological procedure is planned to make sure the quality of precision parts (types of equipment assembling), And reaches all the specifications as the drawing requests. 2.

      7. Ensure the allowance for CNC lathe machining, calculate the size and tolerance
      8. Ensure the cutting parameters
      9. Ensure the production time
      4. The instruction for benchmark of CNC lathe machining
      (i) Definition
      Precision part consists of several surfaces,
      When analyzing the relative relation of the surfaces, you must confirm a benchmark.
      Benchmark is a dot, line, and surface to confirm the part’s dot, line, and surface.
      According to the different functions of the benchmarks, there two categories,
      One is the design benchmark, the other is the technical benchmark.
      (ii) Category
      1. Design benchmark:
      The benchmark to confirm the dots, lines, and surfaces on the drawings 2. Technics benchmark:
      The benchmark for production and assembling. 3. Assembling benchmark:
      The benchmark for confirming the parts’ position in the products when assembling 4. Measure benchmark:
      The benchmark for inspecting the sizes and position 5. Locate benchmark:
      The benchmark for CNC lathe machining. 5. CNC lathe machining Processing Cushion
      Definition
      When the blank is made to finish the product, you will be machining out the metal layer,
      The total of the metal layer is called the total processing cushion.
      The metal layer of every process is called process cushion.
      As to the circle and hole, the processing cushion is on the diameter, called symmetry cushion.
      Why
      The reason, why the workpiece has the processing cushion, is to CNC lathe machining out the tolerance or defect on the workpiece from the last process, for example,
      The cold layer of casting parts, bubble hole of casting parts, the sand layer of casting parts.Oxide skin of forging parts, surface crack of forging parts, decarburized layer of forging parts.
      The surface roughness of CNC lathe machining, etc.
      Precision
      The processing cushion can increase the precision and roughness of workpieces.
      The volume of processing cushion will affect the product quality and production efficiency.
      If the processing cushion is too big, it will increase the CNC lathe machining sum of labor,
      Decrease the production efficiency, increase the loss for raw material, tools and power,
      And increase the production cost.
      Selection
      If the processing cushion is too small, the tolerances and defects from the last process cannot be removed, 
      The tolerances for loading and unloading cannot be removed too.
      The principle is selecting the smallest processing cushion based on high quality.
      Scope of application
      1. Different metal parts CNC lathe machining
      2. Fabrication, box structure, metal structure
      3. Titanium, high-temperature alloy, nonmetal CNC lathe machining

      3 Levels of manufacturers in China
      During the development of more than 50 years, there are 3 levels of manufacturers in China,
      10% is a top-quality manufacturer, 20% middle quality manufacturer, and 70% low quality & cheap price manufacturer.
      The global markets
      At present, many markets are growing all over the world, such as Poland, Czech, Turkey in Europe, Thailand, Vietnam, the Philippines, India in Asian, Brazil in South America.
      Compared to these new growing markets, China has many advantages based on high quality.
      China CNC lathe machining market developing
      In the past, everybody think made in China is for cheap and low quality,
      It’s because China doesn’t have high precision types of equipment and skilled workers,
      It looks like these new growing markets very much.
      But now, 10% top quality manufacturer is fully changed,
      Their core advantage is high quality, they compete with European and North American famous factories.
      Introduction of Sinster
      Ningbo Sinster Machine Co., Ltd is one of 10% top quality manufacturer,
      You have no risk to cooperate with Sinster,
      As many famous brands already choose Sinster and cooperate for long-term,
      Such as Supernova, Pelican, ELKA, Cal-van Tools, Firepro, Tecflo, SEB, Keyence, MAUL, RTS, etc.

      So it seems that Amazon has switched most of their prime member orders to the USPS, probably to save costs. The issue is that the US Post Office does not make deliveries if you are on a private road, unless you have a mailman going outside the policy. I even spoke to the post master of the local office and he's getting complaints from residents who are not getting their packages and have to go pick up at the post office! The mailman is even dropping off a slip that says "Sorry we missed you" or "Delivery attempted" when in fact the package never leaves the post office and they just use that form. It's a joke and my taxes at work, can;t get any more packages from USPS and that includes the majority of them from Amazon. 
      With Amazon's main carrot being delivery and Prime within two days, that's going away for me and for others on private roads unless they switch back to UPS. There is no point if I have to go to the post office to pick it up, no convenience there. Amazon should have negotiated better with the USPS.
