What Do You Know About the Precision Molding of Plastic Parts?

1. Typical precision molding of plastic parts

1) The high processing precision of the plastic parts itself;

2) Typical micro parts usually have high precision molding requirements, both micro-injection and micro-extrusion;

3) Molding of microstructure of larger size products, typical microstructure molding;

4) Large-size products have high requirements on machining accuracy and installation accuracy;

5) The relative high precision of large parts is usually judged by a few thousandths;

6) The matching accuracy between the parts with matching requirements;

7) High requirements for surface quality of precision molding of plastic parts;

8) Deformation-related precision factors are manifested in the control of shape and position tolerances.

2. Typical influencing factors of precision molding process

1) The performance stability of the material;

2) The high precision of the machine itself;

3) Selection and control of processing technology: in addition to reasonable process selection, pressure control accuracy, temperature control accuracy, injection position accuracy, etc.;

4) High-precision control in the precision molding process, such as weight control, thickness control, pipe diameter control, etc.;

5) Environmental impact;

6) The influence of artificial factors.

3. The benefits of precision molding

1) High-precision production can reduce material waste and additional energy loss, and reduce production costs; especially, it can be controlled within a lower tolerance range to maintain stable production;

2) The contribution of high precision to product quality; high precision helps to maintain the consistency of product quality and better assembly performance with matching products;

3) The contribution of high precision to the maintenance of equipment performance; precision molding usually means excellent process stability during processing, which is more conducive to the maintenance of equipment performance;

4) The contribution of high precision to the on-site environment; reduce the workload of waste or subsequent processing and sorting;

5) The contribution of high precision to workers is to reduce the workload of follow-up;

6) The contribution of high precision to the industry is conducive to the promotion of industry brand and influence.

4. Some effective ways to achieve precision molding

1) High dimensional stability material;

2) Special precision machining technology and process;

3) Low stress structural design;

4) Application of new mold technology;

5) Profiling cooling technology, profiling cooling can not only improve the surface quality, prevent weld marks, but also help to ensure product accuracy and prevent internal stress;

6) Auxiliary precision molding technology, gas-assisted and liquid-assisted molding technology;

7) Control technology compensation, especially in the field of some high-performance and high-precision product molding.
