Mold is the mother of industry” this sentence is very familiar to everyone. The importance of mold is more and more recognized, mold design and mold manufacturing technology has also made great progress. Mold processing technology innovation, a variety of new mold materials widely used, mold parts standardization, specialization, etc. , have forced us to…
Before the mold industry in the 1990s, due to the lack of popularity of CNC processing equipment, mold delivery time is long, low precision, rough process. In the mid-to-late 1990s, CNC and other processing equipment was gradually introduced and popularized, greatly improving the delivery speed and mold quality of molds. However, compared with developed countries,…
(1) Requires high precision. A pair of molds generally consists of die, convex mold and mold frame, some of which can be multi-piece die-split. Therefore, the combination of upper and lower molds, the combination of mounting and cavity, and the assembly of modules all put forward high demands on processing accuracy. Precision molds tend to…
Plastic mold processing technology innovation, a variety of new mold materials widely used, mold parts standardization, specialization, forcing us to speed up the design speed, adapt to the development of mold. The improvement of speed requires the design segment to be completed in about 3 days, and the improvement of the precision of plastic mold…
First, plastic mold after the completion of molding product appearance, size, cooperation 1, product surface does not allow defects: lack of material, burning, top white, white line, peak, foaming, whitening (or cracking, pulling), baking, wrinkles. Fuse marks: general circular perforated fuses length is not greater than 5mm, shaped perforated fuses length is less than 15mm,…
1. Plastic material The complexity of the properties of plastic materials determines the complexity of the injection molding process. The performance of plastic materials varies greatly according to different varieties, different brand sizes, different manufacturers, and even different batches. Different performance parameters can lead to completely different molding results. 2). Injection temperature The melt flows…
