JC AUTOCARBON · Curing Molds Factory

Carbon Fiber Curing Molds Factory — Custom Curing Tooling for Composite Parts

We are a carbon fiber curing molds factory. We design and build the molds that cure your parts: autoclave molds, oven-cure molds, compression molds, and RTM molds — steel, aluminum, or carbon composite. Every mold is engineered for the cure cycle: matched thermal expansion, even heating, and vacuum-tight construction. Backed by our full carbon fiber tooling capability, we take your project from drawing to cured parts in one factory.

Engineered for the Cure Cycle

A curing mold lives through hundreds of heat-and-pressure cycles. These five details decide whether it keeps making good parts.

CTE Matching

The mold and the carbon part expand differently when heated. We match the tooling material to your resin and cure temperature, so dimensions stay accurate cycle after cycle.

Even Temperature

Uneven heating causes warpage and weak spots. Our molds are designed for uniform heat distribution across the whole cavity.

Thermal Cycle Life

We choose materials and structures that survive repeated heating and cooling without cracking, warping, or losing surface quality.

Vacuum Integrity

For autoclave and vacuum processes, we build and test sealed tooling that holds pressure — no leaks, no voids in the laminate.

Surface Finish

Mold surface becomes part surface. Mirror polishing options give Class-A finishes that need little post-processing.

Demolding Design

Draft angles, parting lines, and release strategy are planned at design stage, so parts come out clean and cycles stay fast.

From Mold to Finished Part — One Factory

Most mold shops only sell you the tool. We are different: we build the curing mold and then run your production in the same factory — compression molding, vacuum process, and prepreg hot pressing. No handoff gaps, no finger-pointing between suppliers.

Start with a prototype to validate fit and surface, move through our proven development process, and scale to mass production on production molds — all under one roof.

What Our Curing Molds Produce

Our curing molds run production across our full parts catalog — all 22 part categories, from exterior aero to interior trim.

Frequently Asked Questions

What is a carbon fiber curing mold?
A carbon fiber curing mold is the tool that holds a composite layup in shape while heat and pressure cure the resin. It decides the part’s final dimensions, surface quality, and strength.
What temperature can your curing molds handle?
It depends on the mold material. Steel molds handle the highest temperatures and pressures. Aluminum suits most oven and autoclave cycles up to about 180°C. Carbon composite molds match the part’s expansion and typically serve up to 130–180°C depending on the resin system.
Autoclave vs oven curing — which mold do I need?
Autoclave molds must hold vacuum and pressure at high temperature and suit high-performance dry carbon parts. Oven (out-of-autoclave) molds are simpler and cheaper, good for prototypes and mid-volume runs. We recommend the option after reviewing your part and volume.
How many parts can a curing mold produce?
Wet carbon molds typically deliver 100–200 parts. Dry carbon molds can be polished over 300 times. Steel molds last much longer and suit mass production.
How much does a curing mold cost?
Cost depends on part size, complexity, mold material, and target volume. Aluminum and carbon composite molds cost less up front; steel costs more but gives the lowest cost per part at high volume. Contact us for a free quote.
How long does it take to build a curing mold?
A typical project runs about 58 days from design review to approved trial parts. Simple molds can be faster. We confirm the schedule in your feasibility report.
Can you also produce the carbon fiber parts?
Yes. We are a one-stop factory: we build the curing mold and run your parts in-house — compression molding, vacuum process, and prepreg hot pressing. One supplier, one quality standard.
