Automation Plastics - Plastic Injection Molding, Engineering, & Design

Precision Injection Molding:

Automation Plastics is an engineering-oriented company with over twenty years in the business of designing, manufacturing, and processing molds for precision parts. Various unique mold design concepts developed by Henry Derocher, our founder, are utilized in creating molds that are capable of producing millions, and in some cases, billions of small precise parts.

These parts exhibit very close tolerance requirements and minimal flash allowance. We are capable of processing nylon, acetal, polypropylene, and polyethylene for many of these precise needs.

Most of the parts produced at Automation Plastics include exacting features such as threads, sealing surfaces, flash-free parting lines, void free heavy cross-sections, and close tolerances.

Following are examples that typify our ability to provide design, build, and process high cavitation molds that produce close tolerence parts:

160 cavity mold capable of producing 500,000,000 parts/year. The part has a .125 diameter that must be held to +/- .001" and a .013" center orifice that must be flash free.

128 cavity mold capable of producing 350,000,000 parts/year. The part has a .250" diameter sealing surface that is .010" wide that must be completely filled. The vertical flash allowance is .003".

96 cavity mold capable of producing 180,000,000 parts/year. The part has a .342" diameter sealing surface that is .010" wide as well as a center hole that is less than .010" diameter and must be flash free.

32 cavity mold capable of producing 50,000,000 parts/year. The part is a 1-1/4" long tapered flexible dispensing tip with a .019" diameter orifice and a .010" wall thickness.

1 cavity mold capable of producing 18,000 parts/year. (It's a 20 minute cycle!) The part wall exceeds 1 1/2" and must be void free. After molding, the 8" diameter part is machined to tolerences of +/- .005".
