PRODUCTION OF
PLASTIC PARTS

We manufacture plastic parts from blueprints and samples.

The Plastmass Group offers a wide range of production services for processing plastics. We process plastics from our production (PLASTMASS™ plastics) as well as plastics such as Caprolon, polytetrafluoroethylene (Teflon), polyacetal and many more. Our plastics are manufactured under high quality standards in our factory in Russia.

HOW WE CREATE UNIQUE PLASTIC PARTS

The use of automated machining centers ensures excellent quality and precision in machining plastic parts. Our plastics are manufactured in our factory in Russia under high quality standards.

Our specialists can manufacture parts for any industrial plant and machine on request:

  • Conveyor rollers

  • Bushings and plain bearings for any equipment

  • Sliding guides (for chains and belts)

  • Slide plates (track shoes, bearings, guides) for the shafts and sliding mechanisms

  • Sprocket wheels

  • Wheels, pulleys

  • Seals, gaskets, washers

  • Non-standard parts and fasteners

The production time is 1 to 20 days depending on the end product. The minimum quantity is not limited.

TOLERANCES FOR MACHINE-MADE PARTS

Generally the IT tolerance from 9 to 12 is used. In special cases, IT tolerance ranges 7 and 8 are available.

MACHINING

Due to the thermal expansion coefficient of plastics, it makes sense to only carry out the dimensions at room temperature in which the plastic is processed. The tolerances for plastic parts are generally higher than those for metal parts.

VOLTAGE RELEASE

It is recommended to heat plastics before processing and to process them in a preheated state. To rule out the formation of cracks, the material and room temperature should be homogeneous and between 18 °C - 25 °C.

MACHINES

Machines that are used for wood processing are sufficient for processing plastics. The tools should be very sharp and have a large rake angle.

TOOLS

HSS tools can be used for small production quantities. In order to manufacture a large number of products, we recommend using HM tools. The series production of parts with small tolerances requires the use of diamond-coated tools.

LATHE TURNING

Machining with the lathe should be done with a large chip cross-section and a high feed rate. The cutting should be done in one operation.

COOLING

The best heat dissipation is achieved via the chips. A compressed air jet can also be used to remove chips from the work surface and the workpiece.

SAWING

The cutting speed of the band saw should be between 8 - 25 m/s. The saw blade should be made of metal or hard metal. To achieve a better cut, it is recommended to use a saw blade with a tooth spacing of 4 to 6 mm.

MILLING

To prevent overheating when milling, it is advisable to choose the largest possible milling cross section. Milling can be achieved with a high feed rate, a large depth and a medium cutting speed.

REAMING

By rubbing with a reamer according to DIN 206, DIN 212, DIN 219, very tight hole tolerances can be achieved. Due to the elastic behavior of plastics, a minimum machining allowance of 0.1 mm should be taken into account.

THREAD CUTTING

An oversize must be maintained for internal threads in plastics.
Up to M8, the internal thread should be approx. 0.1 mm larger. From M10 the internal thread should be approx. 0.2 mm larger.

FILING & RASPING

Plastics could be processed with wooden rasps. We recommend filing with filing blades.

GRINDING

PLASTMASS™ high-performance polymers can be ground. Commercial grinding belts and grinding wheels with a coarse grain size can be used to grind a workpiece.
