MOLD MAKING & CONTRACT MANUFACTURING

Injection molding is by far the most versatile of all injection molding techniques. The presses used in this process vary in size and are rated based on pressure or tonnage.  Smaller machines can produce very precise plastic parts for surgical applications. In addition, there are many types of plastic resins and additives that can be used in the injection molding process, increasing its flexibility for designers and engineers.

The process itself is fairly straightforward; however, there are many enhancements and customization techniques that can be used to produce the desired finish and structure. Injection molds, which are usually made from steel, contain cavities that will form the parts. Melted plastic is injected into the mold, filling the cavities. The mold is cooled, and the parts are ejected by pins.  This process is similar to a jello mold which is filled then cooled to create the final product.

Businesses choose contract manufacturing for a few primary reasons, all of which make it easier and less expensive to bring new products to the market and distribute them broadly.

The biggest cost benefit of using contract manufacturing is from not having to build a production facility and staff it with workers and managers. Aside from that obvious benefit, companies may save money by hiring a manufacturer based in a low-wage country. The location of the manufacturing plant might also offer savings in energy, overhead, and raw material costs as well as tax savings.

Contract manufacturing frees up people at the hiring firm to stay focused on their core strengths of marketing and, possibly, sales. If the owner has a background in those areas, they may be able to hire fewer people to assist them.
