The testing video of plastic kids chair mold
What is the processing for plastic kids' stool mold making?
Simply first, from rough machining to steel hardening, after steel hardened, we start the CNC milling. We will leave a tolerance of 0.3mm under normal conditions, and then wait for the steel stress to release, we start the finish machining.
Machine operation is very important. Two points need to note:
1. we need to cool the area where needs CNC milling.
2. we must ensure that the depth cannot be greater than 0.08mm during each cutting process.
All of these are to prevent the steel from deforming after the CNC milling and hardening of the steel. Deformation can cause the inaccurate assembly of the core and cavity, which can result in a large amount of manual work on the mold.
