Plastic Injection Molding Companies

Before you decide on a manufacturer it is important that you know some basics about your product and the companies and options available.

TYPE OF PLASTIC:

Firstly you need to know the type of plastic required for your intended product. Plastic injection molding is done using two basic types of plastic; thermosetting and thermoplastic. Both thermosetting plastic and thermoplastic have different properties. Thermosetting plastic can only be heated, molded and set once. Whereas thermoplastic can be heated, molded and shaped again and again. Keeping these different properties in mind you should decide the plastic best suited for your product and it is advisable to discuss this with your manufacturer as well.

SEARCHING Directories:

 The easiest way to search for plastic injection molding companies is by using the lists and directories. Local manufactures are listed in directories and yellow pages. Directories are also available online. Many companies can hesitate while taking small orders so it may take some time before you can fine a company to work with. Hence this can be a time consuming process but it is better to look at various options before finalizing a manufacturer; looking a bit more can get you a better quote. It is better to get at least 3 quotes before you decide on which manufacturer you want to work with. Knowing the market price is always better. You should compare prices and ask for ways to reduce cost. It is possible to reduce costs by changing the materials or even the manufacturing technique.

TYPES OF INJECTION MOLDING:

Injection molding is one of the most common types of plastics manufacturing. The process involves melting of polymer grains and injection of the melted plastic into molds, hence the name injection molding. The plastic is then cooled in the molds and ejected when it has attained its rigid structure again. There are several different types of injection molding. There is co-injection molding, injection-compression molding, push-pull injection molding, metal injection molding, Rheo-modeling, resin transfer molding, microcellular molding, water assisted injection molding and many others. Discuss the types of injection molding your manufacturing company offers. Costs and results vary with the processes so detailed discussion can help you in deciding what will suit your product best.

FOREIGN MANUFACTURERS:

The manufacturers in the US are usually the most expensive. Plastic injection molding companies in India, China and other countries are able to produce plastic products at much cheaper rates. But working with foreign manufactures means more complications. Even though such companies can be found online but complications regarding payment issues, shipping and communication can arise. Furthermore you need to have samples shipped before you can start work with such a company. It is essential to see an adequate amount of samples; this helps you in deciding whether the company is producing products of the desired standard and also whether the company is trustworthy.

Whether you work with local or foreign plastic injection molding companies make sure you’ll be getting quality products at a reasonable amount. And do background check to make sure the company is trustworthy.
