In 1966, five men specializing in molding tool design joined together and founded Decatur Mold. Today, 50 years later—tool design remains one of our strongest capabilities.

We maintain a dedicated staff of highly experienced mold designers. Utilizing state-of-the-art solid modeling design software, our design team puts their expertise to work for high quality, completed mold tool designs.

Basics of Mold Tool Design

img-tool-designExpertly designed injection molding tools should take into account variables like resin viscosity, material shrinkage, gate location or specialty release mechanisms.  Some of the more prominent considerations include:

  • Gate — The type, size, and location of the gate in a mold will have an impact on resin distribution, cycle time, and shrinkage.
  • Number of cavities — Depending on the expected volume of the production run, mold tool design specialists will design molds with as many cavities as is safe and effective to help improve production time.
  • Draft — Included in a design to allow for easy release of a completed part from the mold, the degree of draft will vary by part, surface finish, and other factors.
  • Tool material — Injection molding tools are generally machined from hardened or pre-hardened steel, aluminum, or beryllium copper alloy, depending largely on economic factors and expected production volume — steel tools are more expensive but last longer; beryllium copper tools are less expensive but do not last as long.

Design with Decatur

With a team of expert mold and tool designers, we will design and machine the perfect tool design for your part.

Once you have a fully designed part and determined that injection molding is the best production process for it, you can come to an expected production volume and timeline. From there, you can enlist the efforts of a molding tool design specialist.

At Decatur, we are committed to quality in both our designs and our customer service; our dedicated molding tool design team strives to satisfy both requirements. The team can work with Siemens NX, PTC CREO, Solidworks, Catia v5, and Ideas files, as well as others. Using a detailed CAD drawing of your part and a few basic pieces of information, we will design and machine the perfect mold for your part.
