New England Molding
Better Part Designs Lead to Better Molded Parts.
Before tooling begins, New England Molding reviews customer-supplied part designs for injection-molding manufacturability. We identify features that may create molding challenges, increase tooling costs, or contribute to quality problems during production.
If a design is not well suited for injection molding or may be better suited to another manufacturing process – we explain the concerns and work with the customer to determine the best path forward.
The Quoting Process
Submit your part drawings or CAD files and we’ll return a comprehensive quote tooling and production pricing within 1–2 weeks. Our engineering team reviews every submission before the quote is issued, so what you receive is accurate and includes any design recommendations we’d make before building the tool.
Design for Manufacturability Review
Our team evaluates each design from an injection-molding and production perspective, including:
Part geometry and overall moldability
Draft angles and undercuts
Wall thickness and transitions
Gate and ejector considerations
Material flow and potential defects
Tolerances and dimensional stability
Tolerances and dimensional stability
Opportunities to simplify production and reduce cost
Note on SLA / 3D Printing
Our SLA capabilities are used internally to support engineering and tooling development. We do not offer standalone prototyping services. If you need a prototype before tooling, we can connect you with trusted local resources for prototyping and CAD design.

Our team evaluates each design from an injection-molding and production perspective, including:
- Part geometry and overall moldability
- Draft angles and undercuts
- Wall thickness and transitions

- Tooling complexity and expected maintenance
- Opportunities to simplify production and reduce cost
Collaborative Design Support
We provide practical recommendations to make parts easier to mold, improve repeatability, and reduce the risk of defects. We collaborate with the customer throughout the review process and can connect them with qualified product designers or engineering resources when more extensive design changes are needed.
Customer Approval
Validation & Documentation
All new programs go through a structured validation process before full production. Processing parameters are established, quality protocols defined, and sample parts submitted for your approval before volume runs begin. Retained samples are kept on file.
