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 Vietnam. 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 Vietnam 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 Vietnam Source Moulding Presses from HEMSUN
Industrial plants and contract moulders across Vietnam 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 Sea 10–14 days freight transit, export documentation, and on-site commissioning by factory engineers.

Industries & Component Applications
Our hydraulic compression moulding presses in Vietnam are deployed across mission-critical manufacturing sectors:
1. Industrial Valve & Fluid Handling OEMs
Multi-cavity compression presses for PTFE valve balls (Ø5 mm to Ø310 mm), chevron V-packing sets, valve seats, and flange gaskets with automated bottom-ram soft ejection.
2. PTFE & Fluoropolymer Processors
High-tonnage billet presses (100T to 500T) for compression blocks and skiving cylinders, paired with automated sintering ovens and sheet skiving machinery.
3. Powder Metallurgy & Technical Ceramics
Precision powder compaction presses (20T to 400T) with multi-stage floating die systems for structural sintered gears, electrical ceramic insulators, and ferrite cores.
4. Mechanical Sealing & Carbon Graphite
Dedicated seal ring presses for carbon brushes, expanded graphite packings, and split-cavity bearing bush preforms.

How to Sizing a Compression Press for Your Plant in Vietnam
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.
