HEMSUN ENGG. INDUSTRIES is a dedicated compression moulding machine manufacturer (also specified as compression molding press in US projects) and PTFE moulding machine supplier based in Gujarat, India, delivering heavy-duty compaction machinery directly to Ahmedabad. With over 30 years of specialized press engineering, we manufacture 4-pillar, H-frame, and C-frame presses from 10 Ton to 600 Ton capacity engineered for PTFE, technical ceramics, powder metallurgy, carbon graphite, and composite polymer manufacturing.
Whether your plant in Ahmedabad is setting up a new production line or upgrading manual compression presses, HEMSUN delivers complete turnkey systems—including the press frame, proportional hydraulic power pack, multi-cavity hardened tool steel dies, and digital PLC touch screen automation.
Why Manufacturers in Ahmedabad Source Moulding Presses from HEMSUN
Industrial plants and contract moulders across Ahmedabad choose HEMSUN compression moulding machines to achieve void-free preforms, tight dimensional tolerances, and high-speed multi-cavity output:
- True Factory-Direct Pricing: Sourcing directly from our Dahegam manufacturing works eliminates distributor markups and provides direct communication with the engineering team that designs your press frame and dies.
- Engineered for High-Pressure Compaction: Preforming PTFE requires sustained pressures between 3,000 and 4,500 psi (300 to 500 kg/cm²). Our heavy-duty welded frames and ground tie-bars eliminate platen deflection, ensuring uniform density across thick and thin component walls.
- Turnkey Tooling Integration: We manufacture custom punch and die sets (AISI D2 / EN-31 vacuum-hardened to 58–62 HRC, mirror-polished to Ra ≤ 0.15 µm) and conduct witness trial pressings before dispatch.
- Complete Export & Domestic Logistics: Full support for Same-day freight transit, export documentation, and on-site commissioning by factory engineers.

How to Sizing a Compression Press for Your Plant in Ahmedabad
To calculate the required press tonnage for your component:
$$ ext{Required Press Force (Ton)} = rac{ ext{Total Projected Cavity Area } ( ext{cm}^2) imes ext{Material Pressure } ( ext{kg/cm}^2)}{1000} imes 1.20 ext{ Safety Factor}$$
For example, a 4-cavity PTFE gasket tool with a total projected area of $260 ext{ cm}^2$ pressing at $350 ext{ kg/cm}^2$ requires a 110 Ton to 150 Ton hydraulic press.
