Expert Straight Injection Molding Services for Manufacturers

Straight injection molding is a manufacturing process where molten plastic material is injected directly into a mold cavity under high pressure, creating precise plastic parts. Unlike other processes like blow molding or rotational molding, straight injection molding offers superior dimensional accuracy, faster cycle times, and the ability to produce complex geometries with tight tolerances. It's ideal for high-volume production of consistent, quality parts.

Our streamlined process typically takes 8-16 weeks from initial design to first production parts, depending on part complexity. We follow a structured New Part Development Pipeline: Concept Feasibility (1-2 weeks), Alpha Research with prototypes (2-4 weeks), Beta Development with single cavity tooling (3-6 weeks), Qualifications and first article (2-3 weeks), and Product Launch. Our speed-to-market focus and cross-functional team approach helps accelerate timelines without compromising quality.

We work with a comprehensive range of thermoplastic materials including ABS, polycarbonate, polypropylene, nylon, acetal, TPE, and engineering-grade resins. Our material selection service helps you navigate material and texture science to choose the optimal solution for your application's performance requirements, environmental conditions, and cost targets. We consider factors like strength, flexibility, chemical resistance, temperature tolerance, and cosmetic finish.

Injection molding costs vary based on part size, complexity, material, tooling requirements, and production volume. Our CAD design services start at $110/hour, prototypes range from $100-$300 per part, and production parts can be as low as $0.01 per part for high volumes. We're very upfront with costs from day one, providing detailed pricing breakdowns so you can contribute to optimized design decisions. Contact us for a customized quote based on your specific project requirements.

We implement comprehensive quality control throughout the entire process. Our parts qualification includes detailed molding trial reports monitoring mold fill speed, knit line locations, zone temperatures, and cycle time. First Article Qualification involves 30 inspection points per cavity for critical dimensions and 5 inspection points for non-critical dimensions. We provide complete data to understand process variation and achieve desired Cp and Cpk values before locking down the production process.

Absolutely. Our engineering team specializes in Design for Manufacturing (DFM) optimization. We review your CAD files and implement changes for moldability, including wall thickness modifications, draft angles, gate and vent sizing, and features to minimize sink marks and flash. Our SOLIDWORKS experts can start with your 3D file or model from scratch, providing detailed redlining that documents how design changes improve part manufacturability and reduce costs.

We serve diverse industries including powersports, medical devices, semiconductor and electronics, consumer products, packaging, automotive components, and marine applications. Our team has specific experience with OEMs like Polaris, Boston Scientific, Entegris, General Mills, and Rollerblade. With 25 years of cross-industry expertise, we understand the unique requirements and regulatory considerations of each sector.

Yes, rapid prototyping is a critical step in our process. We offer prototype fabrication ranging from $100-$300 per part, helping you validate final designs for structural and cosmetic verification before investing in production tooling. We guide you in choosing the right prototyping process—whether cosmetic or functional—to advance your design with confidence and minimize the risk of costly tooling changes later.
