Engineering and 3D Prototypes

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.

Rapid prototyping

• 3D Printing – Leading edge “Additive Manufacturing” Quick way for your CAD model to become a physical part
• Injection Molded Prototypes
• Stereolithography (SLA)-functional 3D model for initial review of our design concept
• CU Models (Cast Urethane)
• CNC Machined and fabricated models – Best use if a 3D CAD model is not available and for fabricating a specific shape from a specific material
• Off-Shore Mold Building Alliances
• Low-cost injection molds

Material Selection

• Choose resin and additives based on application
• Review thermal, mechanical and environmental properties
• Consultation for material reaction to fluids or solvents
• Consideration of cosmetic appearance
• Strength and flexibility of a material choice
