What materials do you use to build molds?

We work with P20 and H13 tool steel for production molds, and 7075 and 6061 aluminum for prototype and bridge tooling. Material selection depends on production volume, resin, and surface finish requirements.

Why In-House Tooling Matters

Your Mold Builder Is Also Your Molder

Most shops separate tooling from production. You wait weeks on a mold shop, ship the tool, then wait again for samples. At Ace's, mold making and injection molding happen under the same roof — which means faster iterations, tighter communication, and molds that are designed to run, not just to print.

When the same team that builds your mold also runs your parts, problems get caught in design — not on the floor. That saves you time, money, and headaches.

Tooling and molding under one roof — no hand-off delays
DFM feedback during design, not after
Faster mold trials and sampling cycles
Direct communication — no project managers in the way
Mold storage and long-term maintenance on-site

What We Build

Mold Making Capabilities

From quick-turn prototype tooling to high-volume production molds — we handle the full range.

Aluminum Prototype Molds

Fast, affordable tooling for low-to-mid volume production and design validation. 7075 and 6061 aluminum with 2–4 week lead times.

Steel Production Molds

P20 and H13 tool steel for high-volume, long-run production. Hardened inserts, hot runners, and complex lifter/slider geometry available.

Multi-Cavity Tooling

Single, 2-cavity, 4-cavity, and family molds designed for maximum output efficiency. Balanced runner systems and matched cavity finishes.

3D Printed Bridge Molds

High-temp resin 3D printed molds for ultra-fast prototyping — ready in days, not weeks. Perfect for concept validation before cutting steel.

Mold Repair & Modification

Gate changes, cavity modifications, weld repairs, texture updates — we rework existing molds to extend life and accommodate design changes.

DFM Analysis

Design for Manufacturability review before you cut metal. We catch draft issues, wall thickness problems, and gate location headaches early.

How It Works

From CAD to Molded Parts

01

Submit Your Design

Send us your CAD file (STEP, IGES, SolidWorks, or DXF). No CAD? We can work from sketches, samples, or concept drawings.

02

DFM Review & Quote

We review your part for moldability — draft angles, wall thickness, undercuts — and provide a detailed tooling quote. Usually within 24–48 hours.

03

Mold Design & Machining

Our team designs the tool in CAD, programs the CNC toolpaths, and machines the mold in-house. You stay in the loop throughout.

04

First Article & Sampling

We shoot first-article samples in-house and send them to you for approval. Adjustments are made quickly because the mold never leaves our shop.

05

Production Runs

Once approved, we move straight into production. Your mold is stored on-site and ready to run — no shipping, no scheduling with a third party.

Tooling Materials

We Choose the Right Metal for Your Run

Material	Best For	Typical Life	Lead Time
6061 Aluminum	Rapid prototype molds, concept validation	1,000–10,000 shots	1–2 weeks
7075 Aluminum	Bridge tooling, low-to-mid volume production	10,000–100,000 shots	2–4 weeks
P20 Steel	Production molds, general-purpose	500,000+ shots	4–6 weeks
H13 Steel	High-temp resins, abrasive materials, long runs	1,000,000+ shots	5–8 weeks
High-Temp Resin (3D Printed)	Ultra-fast concept molds, pre-production sampling	50–500 shots	1–3 days

FAQ

Mold Making Questions

How long does it take to build an injection mold?

Prototype aluminum molds typically take 2–4 weeks from approved CAD. Production steel molds range from 4–8 weeks depending on complexity. Rush tooling is available for qualifying projects — call us to discuss.

Do you build molds for outside molders?

Yes. We build molds for companies that run production at other facilities. We provide fully documented tooling with maintenance records. On-site mold storage is also available.

Can you repair or modify an existing mold?

Absolutely. We repair cracked or worn tooling, relocate gates, add or remove features, update surface textures, and modify cavity dimensions. Bring your mold in for a free evaluation.

What file formats do you accept?

We accept STEP, IGES, SolidWorks (.SLDPRT), Parasolid, and DXF. If you don't have a CAD file, we can reverse-engineer from a physical sample or work from detailed drawings.

What's the minimum order for a new mold?

There's no minimum order quantity for tooling — we quote every project individually. Small prototype molds and one-off specialty tools are welcome. We specialize in the jobs big shops turn away.

Do you offer mold maintenance programs?

Yes. We offer scheduled preventive maintenance, cleaning, and inspection programs for molds stored on-site. Ask about our mold maintenance agreement.
