Injection mold design, build and maintenance in the U.S.
Steel prototype, bridge and production molds built in-house for presses from 20T to 1000T, designed alongside the molding team that will run them.
UTP Solutions designs, builds, repairs and maintains injection molds in-house in Michigan, for presses from 20T to 1000T. Tools are built in SPI Class 101 through 105, with cold runners or hot drop and hot manifold systems with valve gate options, in P20, H13, S7, M2 and 420 stainless steel. UTP builds prototype tools in steel with water lines, so early parts produce usable process data and the same tool can serve as a bridge tool and absorb many engineering changes. Aluminum tools are available when a customer requests one. Mold-fill simulation and DFM reviews are done in-house before steel is cut.

Why we build prototype tools in steel
A prototype tool should tell you how the part will behave in production. Steel with water lines cools and runs much like the production mold that follows, so the process window, cycle time, shrink and warp you see on early parts are data you can use, not numbers you have to throw away.
A steel prototype tool can also serve as a bridge tool, supplying parts while production tooling is built, and it can absorb many engineering changes as the design matures. Not every change can be cut into an existing tool, and our engineers will tell you up front which ones can.
That means fewer surprises at validation and a better understanding of how the material and the component perform before you commit to volume. If a customer still wants an aluminum prototype for cost or speed, we will build one.
Why build tools where the parts are molded
- Designed for the press that runs it. Toolmakers and process engineers work in the same building, so gating, cooling and venting are set up for a robust, decoupled process.
- Faster fixes. Repairs, modifications and preventive maintenance happen in-house instead of shipping a tool back out.
- One quality system. Tool build, first article and process validation run under the same Integrated Management System.
Tooling questions
Does UTP build injection molds in-house?
Yes. UTP designs, builds, repairs and maintains injection molds in-house in Michigan, for presses from 20T to 1000T.
What size molds can UTP build?
UTP builds molds for presses from 20T to 1000T, in SPI Class 101 through 105.
Should my prototype tool be steel or aluminum?
UTP recommends steel with water lines for prototypes because it runs like a production tool, so early parts produce usable process data. A steel prototype can also serve as a bridge tool and accommodate many engineering changes. Aluminum tools are available when a customer prefers one.
Can a prototype tool be used as a bridge tool?
Yes. UTP's steel prototype tools can serve as bridge tools while production tooling is built, and can accommodate many, though not all, engineering changes.
What tool steels does UTP use?
P20, H13, S7, M2 and 420 stainless, selected for the resin, volume and part requirements.
Does UTP build hot runner molds?
Yes. UTP builds cold runner molds and hot drop and hot manifold systems with valve gate options.
Can UTP repair or take over an existing mold?
Yes. UTP repairs and maintains customer tools and transfers molds from other molders. If no repairs are needed, first shots are usually ready within 3 business days.
Talk to an engineer, not a call center.
Send the part model, resin and expected volumes. A UTP engineer replies within two business days with a tooling recommendation.
