GF30 Plastic Prototype Parts - Printer Roll Paper Axis

In plastic prototype parts machining, the part is manufactured by machining in the mass of a plastic block by milling machines. In the process of machining, heat will be generated, that would put the effect on the characteristic of plastics. In order to get qualified machined plastic parts, the first important is to use semi-finished products treated with internal stresses, the heat generated during the machining process will lead to the release of internal stress, which results in deformation parts. For materials with high water absorption (such as nylon), dehumidification is needed before processing. The tolerance of plastic is bigger than metal, also plastic thermal expansion coefficient is much larger than the metal. So when machining plastics, these two factors must be taken into account.

Advantages of Plastic Prototype Parts

• Wide selection of the material for the plastic prototype. Direct use of engineering plastic material such as ABS, PP, POM, PEEK, PC, PPS, PA, and PMMA. The mechanical properties close to the injected part.
• Wide range of plastic prototype surfaces. After the machining, we have to do polish to remove the rough edges and burrs. It is also possible to do high gloss polish, painting, printing, sandblasting and chrome plating on the surface.
• The general tolerance for the Plastic Prototype is ISO DIN 2768M for plastics.
• machining offers more potential for threads and undercuts.
