Decatur Mold has been in business for 50 years. Over that time we have developed expertise in a number of fields relating to plastic injection molding.

Production tool building is a process where our expertise is stronger than any competitor. We were founded as a production tool building firm in 1966 and remain a production tool building firm at our core.

Mold Classes

production-tool-buildingAfter prototype tooling has been tested and is ready for full-scale production run of your product, you need to invest in production tooling.

The Society of the Plastics Industry (SPI) defines prototype tooling as Class 105 molds. These molds are designed to serve as a proof of concept, intended for prototype production runs of 500 cycles or less.

Machined quickly and as cost efficiently as possible, Class 105 molds are manufactured from softer materials and often omit more complex aspects, such as specialty release mechanisms.

A true production tool will be a Class 101, 102, 103, or 104 rated mold, each progressively stronger but subject to more requirements. They break down as follows:

  • Class 104 — This mold is designed for a production lifespan of 100,000 cycles or fewer, and for mold materials that are relatively nonabrasive. The mold can be machined from virtually any metal.
  • Class 103 — Designed for medium-sized production runs of 500,000 cycles or less, Class 103 molds have base hardness requirements of 8 R/C and cavity/core hardness of 28 R/C.
  • Class 102 — These molds are designed for high production runs, 1,000,000 cycles or less, and for molding of abrasive materials. Hardness requirements are nearly double that of Class 103 molds.
  • Class 101 — Designed for very high production runs of more than 1,000,000 cycles, Class 101 molds have similar hardness requirements as Class 102 molds. There are additional requirements as well, such as guided ejection, wear plates, and temperature control.

Production Tool Building with Decatur

At Decatur Mold, we can build quality production tooling to meet any SPI Class guidelines. We have a full team dedicated to production tool building, including project managers, engineers, designers, and other personnel.

The team has access to a full range of state-of-the-art design software and production equipment: CNC mills, lathes, drills, spotting presses, and more. With these capabilities, there are no features—shapes, geometries, surface textures, and heat treatments—that we cannot accommodate.

We also understand your need to balance quality and cost. To help facilitate production tool building on all budgets, we offer three different build options: fully domestic production, offshore production by our trusted partner in Shenzhen, China, or a hybrid China-U.S. production.
