Control the Plastic Injection Moulds Manufacturers time; Therefore, as far as you can, the mould is kept in the permissible low temperature, so in respect of shorten the injection cycle, improve the production efficiency, and change your mould temperature, the shrinkage rate will in addition change, the mould temperature will remain stable, and the dimensional accuracy may also be stable, thereby preventing that forming parts.

Third, the common production control. Different shapes, sizes, and ratios of wall thicknesses on the formed parts have certain requirements for your cooling system, and the mould temperature would be to a large extent.

The error caused by the mismatch between the predetermined shrinkage ratio as well as actual shrinkage rate About 1/6 The sum of the error = A + B + D  + D, so it can be seen mould manufacturing tolerances should be lower than 1/3 of the dimensional tolerances with the forming parts, otherwise the mould is hard to guarantee the geometry with the forming parts.

This is a brief description of the reasons the dimensional errors of the shaped regions of the British Plastics Association (BPF) as well as their distribution: The error in mould making is going 1/3, and the error in B a result of mould wear is 1/6 D.
