Mold Creation

Since 1985, Precision Group has built its reputation as one of the world’s leading producers of tools used for injection molding. Our procedure for creating these molds begins with a rigorous and complete investigation of our customers’ requirements, which helps us narrow down the type of mold the customer will need (taking into account their budget and production run expectations). Following this exhaustive period of discovery, we begin the physical tooling process — that is, machining the mold out of metal. Using our 3-, 4-, and 5-axis CNC mills, as well as various Electrical Discharge Machines (EDMs), we are able to build molds to satisfy customer needs for virtually any length or scale of production.

  • Quick Tools (or temporary/soft tools) are molds designed for short/prototype production runs of 100-1000 parts. These low-cost molds are made of aluminum rather than the high-hardness steel used for long production run molds. This is ideal for entrepreneurs and cost-conscious customers as it allows customers to test a short run of plastic parts without suffering any degradation in quality relative to a higher-cost and -quality tools. Quick tools can usually be produced within two weeks.
  • Medium Production Tools are typical molds meant to run under 500,000 plastic parts per year. These standard molds are usually machined from P20 tool steel (a mild steel), and can usually be produced within six weeks.
  • High Production Tools are designed to run more than 500,000 plastic parts per year. These molds represent the highest level of durability available, and consequently are the most expensive and difficult to produce. High production tools can be made of H13 or S7 high-hardness steels, or 420 stainless steel to produce medical plastics. These could be considered the “armored tank” of molds, as they are designed to take a lot of punishment, and they can take six weeks or more to produce.
  • Master Unit Dye (MUD) molds are a lower-cost approach for customers looking to produce small, simple parts. In this system, a customer only pays for a metal insert on the mold instead of the whole mold. The customer will own the insert piece, but will rent space on a larger mold when they want to use it for an injection molding production run. This is ideal for customers looking to test the market with a short-run part.
