Pre-hardened tool steel is a common choice for medium-volume molds because it machines well and needs no further hardening.
Good machinability
No heat treatment needed after machining
Good polishability for general parts
P20, 718, 718H
Medium-volume molds for general plastics
Texturing, polishing
H13 is a hot-work tool steel offering high hardness and thermal fatigue resistance for long-life production molds.
High hardness and wear resistance
Good thermal fatigue resistance
Suitable for high-volume molds
H13, 1.2344
High-volume molds, glass-filled materials
Polishing, nitriding
S136 is a corrosion-resistant stainless mold steel with excellent polish, used for optical and medical parts.
Excellent polishability
Good corrosion resistance
Suitable for clear and PVC parts
S136, 420 stainless
Optical, medical, and corrosive-resin molds
Mirror polishing
NAK80 is a pre-hardened steel with fine, uniform structure that polishes well and holds texture detail.
Fine uniform structure
Very good mirror finish
Good for photo-etched texture
NAK80
High-gloss and textured cosmetic parts
Mirror polishing, texturing
Aluminum molds are machined quickly and cost less, making them suitable for prototype tooling and low-volume runs.
Fast machining and short lead time
Lower tooling cost
Good heat transfer
7075, 6061
Prototype tools, bridge tooling, low-volume production
Machined or lightly polished

| Order Quantity | From prototype tools to high-volume production molds |
Automotive molds are durable production molds for interior, exterior, and under-hood plastic components. Choose them for high-volume parts with strict quality and appearance requirements.
A range of materials is available, including P20 / 718 Pre-Hardened Steel, H13 Hardened Steel, S136 Stainless Mold Steel, NAK80 Mold Steel, Aluminum Tooling. The best choice depends on strength, appearance, operating environment, and budget. Our engineers can help you select the right one during the quote review.
Achievable tolerances depend on material, part size, and geometry. Typical values are listed on this page, and tighter tolerances can often be held on critical features. Share your drawing and we will confirm during the DFM review.
Yes. We support everything from a single prototype to ongoing production programs, so you can scale without changing supplier.
Cost depends on material, part size and complexity, quantity, tolerances, and finishing. Upload your CAD model and drawing to receive a quote, and our engineers can suggest design changes that reduce cost.
We accept common 3D CAD and 2D drawing formats, including STEP, STP, IGES, STL, SLDPRT, X_T, DXF, DWG, and PDF. If your format is not listed, please contact us.
Lead time depends on process, quantity, and finishing. Prototypes can often ship within a few business days, and we ship worldwide. Contact us with your requirements for a lead-time estimate.
Mold life depends on steel, material, and maintenance, and is discussed during mold design review.
