Lost Foam Casting Molds

• Process-specific & Complex Structure Adaptation: Designed exclusively for foam pattern forming, it can realize integrated forming of complex castings such as special-shaped parts, multi-cavity parts, hollow structures and curved contours without splitting the mold. The casting structure has high degree of freedom, solving the complex shaping problems that are difficult to achieve by traditional casting.
• Diversified Materials & On-demand Adaptation: Mold materials include aluminum alloy (A356, ADC12), cast iron (HT200, HT250), resin mold, wooden mold, etc. Aluminum alloy mold has uniform thermal conductivity and high forming precision, service life ≥8000 cycles, suitable for medium-batch production; cast iron mold has high strength and wear resistance, service life ≥15000 cycles, applicable to mass production; wooden/resin mold is cost-effective and fast-processing, suitable for single-piece/small-batch trial production.
• Near-net Shape Forming & Excellent Precision: Cavity dimensional tolerance ≤±0.05mm/m, surface roughness Ra≤3.2μm, casting machining allowance reduced to 1-2mm, near-net shape forming reduces subsequent machining costs by 30%-50%. The foam pattern fits the mold precisely, avoiding the parting surface misalignment problem of sand casting, with good casting dimensional consistency and qualification rate ≥97%.
• Dry Sand Molding & High Efficiency Environmental Protection: Adapt to lost foam dry sand vibration molding process, the mold does not require complex sand core structure, simplifying the production process and shortening the molding cycle by 25%. No binder or release agent, no sand hole defects in castings, and the production process is environmentally friendly and pollution-free, meeting the requirements of green casting.
• Full-scenario Adaptation & Flexible Customization: Suitable for castings of various materials such as gray iron, ductile iron, aluminum alloy, carbon steel and stainless steel, casting weight covering 0.5kg-1000kg. It can customize cavity structure, exhaust groove and positioning pin according to customer casting drawings, meeting the production needs of complex castings such as automotive parts, construction machinery components and general mechanical accessories.

• Automotive Industry: Engine blocks, gearbox housings, rear axle housings, exhaust manifolds, automotive brackets and other complex castings.
• Construction Machinery: Excavator arm, loader bucket, crane slewing bearing, hydraulic valve block and other high-strength castings.
• General Machinery: Pump bodies, valve bodies, gearbox housings, motor end covers, compressor casings and other complex structure castings.
• Mining Machinery: Crusher jaw plate, lining plate, mining machinery connectors and other wear-resistant castings.
• Other Fields: Marine parts, medical device accessories, aerospace auxiliary structural parts, construction machinery accessories, etc.

​

• Test Reports: Provide raw material quality reports, mold dimensional accuracy test reports, cavity surface quality test reports, foam pattern adaptation test reports, etc.
• After-sales Commitment: For non-human damage, mold warranty is 1 year or agreed cycles (whichever comes first); provide free mold maintenance guidance, foam forming process support, test mold technical services, and lifelong mold repair and renovation services.
• Quality Standards: Strictly comply with domestic and foreign industry standards such as GB/T 6414 Casting Dimensional Tolerance Standard, GB/T 9439 Gray Iron Castings Standard, JB/T 5105 Technical Conditions for Casting Molds, ASTM A901 Lost Foam Casting Standard.
