Die Cutting vs. Molding: Which Fits Your Project?
Both processes make custom silicone gaskets, but they fit different needs. Die cutting cuts gaskets from silicone sheets. Molding shapes gaskets inside a metal mold. Here is a simple comparison to help you choose:
Factor | Die Cutting | Molding |
|---|---|---|
Tooling Cost | Low (simple cutting die, or no die with CNC cutting) | High (custom mold needed) |
Lead Time | Fast — samples in days | Longer — mold making takes weeks |
MOQ | Low, prototypes welcome | Higher, to cover mold cost |
Best Shape | Flat, 2D shapes | 3D shapes with lips, ribs, or curves |
Thickness | 0.5 mm – 25 mm (sheet based) | Almost any thickness |
Tolerance | ±0.1 mm to ±0.13 mm | Tighter, set by the mold |
Unit Cost at Low Volume | Lower | Higher |
Unit Cost at High Volume | Higher | Lower |
Our advice
If you need a flat gasket, a fast sample, or a small to medium order, die cutting is your best choice. If you need a 3D shape or a very large order, molding will save you money in the long run. Not sure which one fits? Send us your drawing — our engineers will check it and suggest the best process for free.
Custom Shapes We Can Cut
Our factory can die cut silicone gaskets in almost any flat shape, including:
How to send us your design: A DXF, DWG, PDF, or STEP file is perfect. No drawing? No problem — send us a sample, a photo with sizes, or even a hand sketch. We will make the production drawing for you and confirm it before cutting.
Material & Thickness Options
We keep a wide range of silicone materials in stock, so we can start cutting fast:
Material Type | Thickness Range | Hardness | Best For |
|---|---|---|---|
Solid Silicone Rubber | 0.5 – 20 mm | 30 – 80 Shore A | General sealing, high pressure joints |
Silicone Sponge | 1 – 25 mm | Soft to firm | Low-pressure seals, dust and water protection |
Silicone Foam | 1 – 25 mm | Very soft | Gap filling, soft cushion seals |
Fluorosilicone (FVMQ) | 0.5 – 10 mm | 40 – 70 Shore A | Fuel, oil, and solvent contact |
Fiberglass Reinforced Silicone | 0.8 – 6 mm | 60 – 70 Shore A | Stable size, no stretch, flange use |
Conductive Silicone | 0.5 – 6 mm | 50 – 75 Shore A | EMI shielding, anti-static uses |
More options on request: FDA food grade, medical grade, high temperature (up to 300°C), flame retardant, metal detectable, and adhesive backing (acrylic or silicone PSA).
Standard colors include translucent, red, white, black, gray, and blue. Custom colors are available — just send us a Pantone number or a sample.
