Mold Design Services

---

At True Position Plastics, we provide complete mold design services for both prototype and production tooling. Every mold design is tailored to your part geometry, production volume, material selection, and press requirements. We design molds that fit your project budget and meet your company standards. 

Prototype Mold Designs (Class 104/105)

We offer quick-turn and bridge tooling solutions, including:

• MUD base insert sets
• Round Mate-style inserts
• Custom prototype tools
• Designed for fast iterations, early validation, and lower-cost entry into production.

Production Mold Designs (Class 101, 102, 103)

We design production plastic injection molds for many industries such as medical, consumer, automotive and defense. All of our mold designs are optimized for long-term durability, ease of maintenance, and repeatable part quality. We can design plastic injection molds to your specific standards or we will apply best practice industry standards based on our knowledge and experience. We design molds that use as many readily available components as possible so that lead times are reduced. 

Hot and Cold Runner Options

We design molds for both hot and cold runner scenarios:

• Cold runner systems: cost-effective for low-to-medium volume or multi-material applications
• Hot runner systems: optimized for reduced waste, balanced flow, and higher efficiency
• Valve gate systems: ideal for cosmetic parts, sequential gating, or shear-sensitive materials
• Hot sprue bushings: simplified hot drop systems for direct gating and minimized residence time

No mold design is too complex for True Position Plastics

We have designed plastic injection molds for very well known brands in the consumer, medical and defense industries.

We design plastic injection molds for a wide range of configurations:

• 3-Plate molds for center gating and flexibility in gate location
• Stripper plate molds for uniform part ejection without ejector pins
• Reverse injection molds for back-gating or specialized part designs
• Insert molding and overmolding tools for multi-material or metal/plastic integration
• 2K molds for complex double shot parts.
• Side-actions, lifters, and unscrewing mechanisms as needed for undercut removal 

Industries We Serve

We design molds for a broad range of industries:

• Automotive
• Medical devices (ISO-13485)
• Consumer products
• Electronics
• Industrial components
• No project is too simple or too complex.

Whether you're developing a prototype or scaling to high-volume production, we design plastic injection molds that are robust and built to run longer, perform better, and stay cost-efficient.
