We engineer the mold before we ever start cutting steel.

Our DFM and tool design work doesn’t just catch problems early, it lowers what the tool costs to build, shortens your cycle time, and produces a mold that holds up for the life of the program.

Why DFM Matters Before Tooling Begins

Most tooling problems aren’t discovered on the shop floor- they’re discovered after the tool is already cut, when a part won’t eject cleanly, a wall thickness causes warping, or a gate location leaves a visible defect on a cosmetic surface. By then, fixing it means rework, delays, and unplanned cost. Our engineering team reviews your design before any steel is cut, so problems get caught on a screen instead of in a mold.

The same review also decides what the tool costs. Gate strategy, parting line, and draft aren’t cosmetic decisions- they determine whether your part runs in a straightforward two-plate tool or one carrying slides, lifters, and extra plates. Those choices get locked in early, and they’re expensive to revisit once steel is cut.

What Our Engineering Review Covers

01.

Design for Manufacturability (DFM) Analysis

We review your CAD before quoting and flag the geometry that will cause problems in steel: non-uniform wall thickness, insufficient draft, undercuts, and features that can’t be formed in a straight pull.

02.

Mold design in Cimatron and Solidworks

Purpose-built mold design software, not general-purpose CAD with tooling bolted on. Cavity and core layout, runner and gate design, cooling, ejection, and electrode design for EDM detail.

03.

Material and steel selection

Resin guidance based on part function, tolerance, and cost- plus the mold steel to match your expected volume and how abrasive your resin is.

04.

Fast turnaround, clean data transfer

Send a STEP file and keep your native CAD in-house. No format back-and-forth, no lost geometry, no reason to hand over proprietary model data you’d rather protect.

Where Engineering Decisions Show Up in Your Cost

Three decisions we make before steel is cut, and what each one costs you if it’s wrong.

Parting Line and Draft

The parting line sets your direction of draw. Anything that can’t be formed in that direction needs a slide or a lifter- more steel, more moving components, more maintenance, more cycle time.

Draft is what lets the part release cleanly once it’s there; too little and you get drag marks, stuck parts, and ejector witness on visible surfaces (textured surfaces need more draft than polished ones). Getting both right upfront often removes a side-action from the design entirely.

Gate Strategy

Gate location determines how the cavity fills, where knit lines land, and where the gate vestige ends up on a cosmetic surface. It also drives the architecture of the tool itself- whether you stay in a simple two-plate build or get pushed into a three-plate or hot-runner tool you didn’t budget for.

We settle gating early, weighing upfront tooling cost against runner scrap on every shot for the life of the program.

Cooling and Cycle Time

Cooling is the largest share of the molding cycle, and the layout of your water lines decides both how fast the part comes out and how evenly it shrinks. Uneven cooling shows up as warp and dimensional drift shot to shot.

We design cooling into the tool from the start rather than working around it- because a second or two of cycle time compounds across every shot you’ll ever run.
