Making Plastic – Plastic Injection Moulding

Curtis was selling hand held margin trimmers, color coordinated to match Curtis’s color scheme, for .95 I think, and they were beginning to sell. Life was good.

These molds can be made to almost any shape or size. To put it simply, injection molding is the process of forcing melted plastic in to a mold cavity. Once the plastic has cooled, the part can be ejected. It is useful when the parts are too complex or cost prohibitive to machine. With this process, many parts can be made at the same time, out of the same mold.

It removes a whole lot of EDM work and hand fitting, particularly of contoured shut-off surfaces. It makes a surface that’s nearer to the CAD model. You can even do away with stoning and polishing which would otherwise take a whole lot of time and labor costs. It could lessen the required number of grinding steps. Work on plastic injection molding is hastened and delivery dates are shortened.

The HSS steel drill bits are generally used for manufacturing and machinery industries. It is said that if there will not be any HSS, no modern metal plastics processing will survive. The advent of HSS drill bit has increased the metal cutting speed of the tool and become faster and faster.

5S is just one part of the lean manufacturing process. It is also essential that everyone follows through, so the benefits can be permanent. It is not enough to paint some outlines of wrenches and then leave them laying about randomly.

And obviously if you are going it alone, than saving a 0,000 here and there by keeping the plastic extrusion , (custom made plastic pieces) down to a minimum makes good economic sense.

He, (I’ve never seen a she, though I heard about one once) starts work at either 6 or 7 a.m. I also have never known a mold maker who started later on a regular basis. He typically works a 9 or 10 hour day and often 5 hours on Saturday. Before Asia became a mold making force to be reckoned with, there was basically unlimited overtime for everyone.
