Capable project management from design to final part. One-stop service for all of our clients’ plastic injection molding.

The life of an injection mold is directly related to the type of mold, the type of material injected into it, and the number of parts produced.

Since injection molding represents the most common method of plastic parts manufacturing, the list of products can range from bottle caps to car parts. More complex parts are made out of a combination of two or more materials through a special process called overmolding.

Custom plastic injection molders employ computer-aided design (CAD) software or similar to produce custom molds machined with different disciplines out of solid metal and generally have two halves that will come together during the mold assembly process.

American inventors and the first plastic injection molding manufacturers, brothers Isaiah and John Wesley Hyatt patented the very first injection molding machine in 1872. Despite its seemingly simple original design, this machine made the manufacturing process infinitely easier. It also served as the prototype for the sophisticated machines that we use nowadays, since the principle is much the same to this day.

As a reputable plastic injection molding company, we offer an array of materials that can be used in the production process. Learn more about various materials that we use at our materials page.

During and after the injection molding, and before shipping the components to the client, the parts go through a thorough quality inspection.

A plastic injection company is a business that handles plastic molding manufacturing. Typically, these companies operate on a medium to large scale, producing large quantities of plastic molds and related products for a diverse range of applications.If you’re looking for one of the best plastic injection molding companies, we’re here to help you with our expertise and precision.

Custom injection molders design and manufacture custom molds and/or custom parts from a mold for the customer at small, medium, and large volumes.
