Molding Plastic

The wonderful thing about plastic injection molding is the low cost of the parts being produced when you need a large volume of parts. The downside is the cost of injection molding tooling. The toolings, or the molds, range in price anywhere from $2000 for a simple one, to over a hundred thousand dollars for a big and complex injection mold. The way the injection molders figured out how much to charge per part was to weigh the part complete with runner to determine how much plastic resin is used for each part. The size of the part determines what size injection molding machine must be used, and how big the mold is etc.

Purchasing the box, some assorted socket rails, and some additional clips for the socket rails, I took the box home with me to see how well it would stand up as a replacement. The box is quite simple in construction. It's a plastic injection molding case made of a very thick plastic. The case consists of a flip open lid (with two latches that are padlock compatible) covering a deep top storage area, and three drawers that are very similar to the large rolling tool chests that many professionals and advanced amateur home mechanics have in their garages. When you flip the lid open, the lid will immediately release the latching mechanism for the three drawers. Unfortunately, the lid does not contain any hinges or tethering that prevent it from flopping open and hitting itself on the back of the tool box. This was my only gripe involving the tool box.

High volume injection molding capabilities and precision tool makers in their China Factory allow us to provide quick-turn service on medium to high volume orders, where they build dedicated long-run production molds. The company specializes in high volume plastics injection molding custom plastics jobs. High-end second-op machining is also available. Their PVC and plastic injection molding factories in China manufacture very high quality products that are extremely cost effective. Their warehousing and distribution facility in Austin, Texas also allows them to service custom injection molding projects in Dallas, Houston, San Antonio and other cities across molding the country very easily.

Injection Molding is the most advanced typical method of molding rubber products. Injection molding produces the most consistent results by automating all aspects of how the rubber gets into the mold. In injection molding, the rubber is worked and warmed and then squirted into the mold at controlled speeds, pressures and temperatures. Advantages of Injection Molding are: Provides the maximum product consistency, Allows the most control of flash, Because the rubber is warmed before going into the mold, fastest cycle times, Disadvantages of Injection Molding.

About 2 years ago I purchased a tool set. It came with a wonderful set of tools, but a really low end, thin and hollow plastic injection molding case that belies the namesake and tradition. Needless to say, the case finally gave up the ghost this past week. I began shopping for a replacement tool box for the old set that has since grown to over 200 pieces. Wanting some level of organization that is needed on the trail while off roading, the plastic tool box intrigued me due to its thick plastic construction and it's similarity to a larger tool chest with extendable drawers. Its size and depth allowed me to place it in the same spot as where I held the old plastic injection molding case in my truck.
