Prototyping

Test Early. Refine Quickly. Move Forward with Confidence.

Plastic prototype manufacturing offers a critical advantage during product development. Holding a physical part rather than relying solely on CAD gives teams the ability to assess fit, function, and manufacturability before committing to full-scale production. Adjustments at this stage save time, reduce cost, and help prevent design issues from reaching the manufacturing floor.

At Sussex IM, plastic prototyping support is more than a one-size-fits-all service. Our engineers evaluate your goals and timeline to recommend the best approach, whether that involves a quick-turn 3D printed sample or an aluminum mold for short runs.

Plastic Injection Prototyping Services to Support Every Stage

3D Printed Prototypes

Using our Objet30 Pro PolyJet printer, we can generate detailed physical parts from 3D CAD files within hours. This method provides an accurate look at part geometry and helps teams evaluate ergonomics, tolerance stack-up, and design feasibility early on.

Prototype Molds

When functional testing requires molded plastic, we build aluminum or soft steel tooling for limited-run production. These prototype molds are ideal for evaluating material behavior, refining gate locations, and validating part performance under real molding conditions without the full investment in hardened steel tooling.

Why Customers Use Prototypes at Sussex IM

Identify design issues before committing to full production
Test plastic part performance and material selection
Evaluate form, fit, and assembly
Gather stakeholder feedback with real samples
Validate molding conditions and optimize cycle times

Our engineers work directly with your team to review results, recommend improvements, and refine part design for better outcomes in full production.

Prototype to Production All Under One Roof

As a full-service plastic injection molding manufacturer, Sussex IM supports every phase of your product lifecycle. Prototyping connects directly to our tooling, molding, and automation services, keeping development fast and cohesive.
