A compression mold is a heated steel tool used on a hydraulic press to shape thermoset materials such as SMC, BMC and phenolic. We are a specialist compression mold maker in India, building molds for custom compression molding and thermoset molding companies abroad.
Why buy compression molds from India
Specialist, not generalist
Thermoset compression molds are our main line, not a side business of an injection shop.
Engineering first
A DFM report on your part before you commit, shared online.
Clear communication
One engineer as your contact, with regular photo and video updates through the build.
Competitive cost
Indian tool-room costs with hardened, polished cavities built to last.
Compression molding tooling we export
As a compression mold manufacturer, we build complete tools and the parts that keep them running. Every mold is designed around your part, your material and your press.
| Tooling | Typical parts | Material |
|---|---|---|
| SMC molds | GRP enclosures, meter boxes, junction boxes, covers and panels | SMC (sheet molding compound) |
| BMC molds | Insulators, busbar supports, terminal blocks, breaker housings | BMC / DMC (bulk molding compound) |
| Phenolic molds | Switch and socket bases, fuse carriers, heat-resistant parts | Phenolic (Bakelite), melamine, UF |
| Multi-cavity molds | Small electrical parts made in high volume | BMC, phenolic, melamine |
| Replacement cavities and inserts | New cavities or inserts for an existing mold base | H13, W302 ESR |
See our SMC molds and BMC and DMC molds pages for design details, or recent projects with photos from our tool room.
Steel, heating and documentation
Export molds have to work first time in a press we may never see, so we agree the details up front and document them.
| Item | What we supply |
|---|---|
| Cavity and core steel | H13 or Böhler W302 ESR, hardened; P20 for plates and holders |
| Steel traceability | Steel bought from known suppliers, with supplier certificates on request |
| Heating | Cartridge heaters and thermocouples to your voltage and controller |
| Press fit | Mold height, clamping, ejection and lifting points to your press data |
| Drawings | Mold assembly drawing and 3D model (STEP) on request |
| Trial record | Trial video, key settings and first-off parts |
| Spares | Recommended spares list: ejector pins, heaters, thermocouples |
New molds from our tool room
Recent new compression molds, photographed in our tool room. Cavities are machined from solid hardened steel on our VMC, then polished and fitted to their cores before trial.
From part design to mold: our SMC enclosure study
Every export project starts with a feasibility study of your part. This film shows our study of an SMC electrical enclosure: the part, the mold concept and the checks we make before any steel is cut.
How an export project runs
- NDA and drawings. We sign your NDA, then you share the 3D model, material and press details.
- Online DFM review. We send the DFM report and discuss it on a video call.
- Quotation. Mold price, steel, lead time and delivery terms.
- Build with updates. Photos and videos at each stage of machining and fitting.
- Trial video and parts. A recorded trial and first-off parts for your approval.
- Export crating. Rust protection and export crating for sea or air freight.
Mold trials: watch it run before it ships
Every mold is tried on a press before dispatch. Export buyers receive the trial video and first-off parts for approval, so you see the mold working before it leaves our tool room.
Packing and shipping
Finished molds are cleaned, rust-protected and painted on the outside, with the cavity surfaces oiled and wrapped. Spares and loose parts are packed separately and listed. Delivery terms are agreed in the quotation; the nearest sea port to our tool room is JNPT (Nhava Sheva) near Mumbai.
What to send for a quote
- 3D model of the part (STEP or IGES) and a 2D drawing
- Material: SMC, BMC, phenolic or other, with grade if known
- Annual volume and number of cavities wanted
- Press tonnage, platen size, daylight and ejection layout
- Heating supply: voltage and controller type
- Delivery country and preferred delivery terms
