Zhengtai Castech is a total solution provider for specialty castings, with a particular focus on Lost Foam Casting (LFC), precision casting, and centrifugal casting.
Our services include turnkey project support, casting process suitability evaluations, and feasibility studies comparing LFC with conventional no-bake sand casting and more complex or costly lost-wax processes. We also provide solutions for complex alloy tubes and pipes using reliable and proven centrifugal casting methods.
Our technologies are designed to reduce resin-coated sand consumption and overall operating costs, particularly for thin-walled and complex castings, through vacuum-assisted and multidirectional vibration compaction systems suitable for semi-automatic and fully automatic production lines.
Our services also include die and mold design, 3D modeling and studies, and prototype white mold development using EPS or STAMMA-based beads. We leverage our established white mold production, assembly, and casting development capabilities through dedicated manufacturing facilities in China.
Zhengtai Castech also plans to establish dedicated technical centers across major foundry clusters in India to provide pre-sales and post-sales support for equipment, technologies, dies, and molds related to LFC, precision casting, wax-replacement processes, and centrifugal casting.
Our scope further includes innovative refractory coatings for a wide range of casting processes, energy-efficient drying oven systems, glues, pads, and assembly jigs for both manual and automated operations.
Complete white-area and black-area technology, seamlessly connected by foundry engineering and rigorous project implementation.
EPS and STMMA pattern production, precision shape moulding equipment, pattern cluster assembly, automated dip coating, climate-controlled drying chambers, and environmental control.
Automated sand rain filling, 3D multi-frequency vibration compaction tables, automated flask transport, negative pressure vacuum manifolds, pouring stations, cooling tunnels, shakeout, and 95%+ sand recycling.
Process design, casting gating simulation, capacity calculations, complete 3D plant layouts, GA drawings, utility balance (power, water, air, vacuum), melting shop integration and site implementation.
A specialized Lost Foam route for suitable large, intricate and geometrically complex castings where conventional synthetic-wax pattern processes may become cumbersome, costly or difficult to scale.
