Liquid Injection Molding

Reaction Injection Molding (RIM) produces parts with intricate detail that are dimensionally stable, chemically resistant, physically tough, and wear resistant. This process is an excellent choice for larger plastic parts produced in short run or low volume production quantities. Considerable design freedom is possible, including thick and thin wall sections that are not good for injection molding, due to the uniform shrink characteristics. Foamed polyurethanes are natural thermal and acoustic insulators. Excellent flowability allows for the encapsulation of a variety of inserts.

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, liquid Houston, San Antonio and other cities across the country very easily.

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 injection 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.

Cast kirksite cavities from SLA models can provide excellent rapid tools for prototype and bridge to production injection molding parts. Parts can be molded in two to three weeks in any thermoplastic production resin, this technology has been around for many years, but with the growth of stereolithography and the need for rapid turnaround of plastic parts in the correct production material, the kirksite approach has re-emerged. More complex parts can be made using handloads. Injection molding tapers are important and are best incorporated in the master file. One of the advantages of kirksite aluminum/zinc alloy moulds is the ease of making geometry modifications by either welding or adding inserts. Another main benefit is the ability to mold most materials.

Purchasing molding 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 liquid 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.
