PLASTIC PART DESIGN AND ENGINEERING FOR PLASTIC INJECTION MOLDING
At Stelray Plastic Products, Inc., we are often asked to assist in the plastic part design development and prototyping of new product ideas for our customers. If “speed to market” is your concern, often times Stelray in house 3D printing services can be the interim solution. As a full service plastic injection molding company, we offer a number of product design, engineering services and material options to help develop, validate form, fit, and function of your part for successful plastic injection molding.
Whether you need two parts or 2,000,000 parts, Stelray can accommodate your plastic injection molding requirements. Allow us the opportunity to consult with you and we will recommend the best tooling and material options to meet your needs.

Plastic Injection Molding Resources For Part and Mold Design
When making parts designed for injection molding, incorporating draft angles is an important consideration for consistent quality parts.
Deciding the mold runner system is one feature of the mold design based on factors of the part design and features. The two options are a hot runner and cold runner which both have advantages and disadvantages.
