Injection mold manufacturing can be roughly divided into the following steps: First, the process analysis of plastic products. Before the mold design, the designer should fully analyze whether the plastic products meet the injection molding processing principle, and need to carefully negotiate with the designer of the product, and a consensus has been reached. This
Bench of mould irrespective of the machine tool or technique used to manufacture the various parts of the mould, the final responsibility for the finishing of the individual parts and for fitting them together lies with the bench fitter. The mould finishing and assembly procedure adopted by the bench fitter varies from toolroom to toolroom;
Talk about mould cooling One fundametal principle of injection molding is that hot material enters the mould, where it cools rapidly to a temperature at which it solidifies sufficiently to retain the shape of the impression cycle.while the melt flows more freely in a hot mould, a greater cooling period is required before the solidified
Feed system of mould It is necessary to provide a flow-way in the injection mould to connect the nozzle (of the injection molding machine) to each impresion. This flow way is terned the feed system. Normally the feed system comprises a sprue, runner and gate. these terms apply equally to the flow-way itself, and to

injection molding issues of PC+ABS Rounded pellets usually are hot-cut, cylindrical pellets are usually strand-cut so most likely different extruders were used. This (change in extruders) may effect compounding of the materials and thus properties, but your supplier should have done QC testing to know product is the same. Again, this may be where
The reason causes mold with hot runner leakage Is the leakage on the outside of the mold or internally. Possible causes for external leaks are worn probe seals or improper cleaning when being maintenance. Internal leakage may be caused by shooting through when manifold in not fully up to temp or wear on the
INJECTION MOLDING PROCESS FOR PP PLASTICS “Plastic properties are the basis of injection molding technology”. Mastering the technological properties and characteristics of various plastics is a basic professional knowledge that every injection molding worker must know. The performance of plastics is the basis for setting “injection molding process conditions”. It is also the reason
