Precision Group offers the full-service manufacturing of molded plastic components for a wide range of industries. Our expertise in precision tooling manufacturing includes a wide variety of molds, including prototype aluminum molds, multi-cavity, stack molds, rapid tooling, insert molds, gas-assisted, thin wall, and hot runner molds.

To help you better understand the benefits of each injection molding option, here’s a quick breakdown:


Aluminum is one of the top materials for prototyping. Prototype aluminum molds offer higher production, better quality, and enhanced reliability.


Multi-cavity molds are ideal if you have thousands of moving parts every month. By increasing your product capacity, since there are so many mold cavities, production improves.


In stack injection molding, molds are put on top of one another, and each mold level creates a product. This significantly enhances the product output, allowing more products to be made faster. This is great for large products and results in quicker delivery times.


Rapid tooling incorporates rapid prototype plastic injection molding with standard tooling procedures to create prototypes and other molds at a faster rate. This decreases costs and allows for quicker manufacturing.


Insert molds include different types of materials, such as metals and plastics. By combining these materials, the products are overall more durable. This is especially helpful in industries such as medical and electronics, which have small parts that require the most reliability and design flexibility.


Gas-assisted molds are used to develop large plastic components with more complex designs. This option offers some of the most design flexibility in injection molding.


Thin wall molds are used to mass-produce tiny plastic components. This is especially useful in industries such as automotive and medical, which require small, light parts and quick manufacturing. Thin wall molds have a lower cost per part and quicker delivery times than many other options.


Hot runner molds are injected in cavities with molten plastic. The molds in these cavities imitate the shapes of the parts in production, quickly bringing each product through the development process. This results in a lower cost, shorter cycle time, and more design options.


Precision Group is an industry-leading designer and manufacturer of injection-molded plastics and tooling. In order to offer cost-effective injection molding, Precision Group offers Master Unit Die and Round Mate quick-change mold frame systems. These systems achieve lower tooling costs with the benefit of quick-to-market manufacturing.

We also offer mold repair. That includes mold transportation to and from the customer, in-house mold repair, on-site mold repair, and preventative maintenance. No matter the size or complexity of the product, we can help.

At Precision Group, we always strive to be on the cutting edge of technology and deliverability.
