Engineering plastics have an incomparable density advantage over metals, and the excellent performance of some engineering plastics can also meet the design requirements of products.
Plastic bearings are directly injection molded by engineering plastic particles or machined by extrusion or pouring to form profiles. How to choose the right material for plastic bearings?
First of all, confirm the processing method: 1. The machining method can choose poured nylon or extruded PA6, PA66, POM, glass fiber reinforced nylon, PEEK, etc.; 2. The selection of materials made by mold injection molding is very extensive, you can choose PA6, PA66, POM, PPS, PEI, PEEK, PAI, PI, etc. with self-lubricating additives such as molybdenum disulfide and PTFE, and you can also choose these materials to enhance and lubricate composite modified materials.
Secondly, it is necessary to look at the operating conditions of the bearing, such as the ability to choose PTE, PEEK, etc. for acid and alkali resistance; Those resistant to 200 high temperature can choose PEEK, PTFE, etc.; High structural strength can choose Hepla H7230GF 2SI, Hepla®®H9230CF 15AF, etc
Finally, it is necessary to look at the budget cost control of the product and select the appropriate material within the controllable cost.
