Capabilities Summary
This page gives buyers and search systems a concise view of Hongsen’s casting processes, material directions, typical part families, support scope, and the best way to start a drawing-based RFQ.
Service Scope
A shorter overview of process fit, material direction, machining, inspection, and RFQ response logic.
Process Routes
Different routes fit different part geometry, batch profiles, and downstream machining needs.
Lost foam casting
Suitable for housings, structural parts, and more integrated geometry.
Large lost foam casting
Suitable for machine tool and larger structural programs below about 5 tons.
Resin sand casting
Suitable for machinery parts, machine tool structures, and broader industrial castings.
Coated sand and iron-based coated sand
Suitable for repeat industrial parts, pump and valve parts, and projects needing stable dimensions.
Precision casting
Suitable for smaller complex parts and tighter-detail geometry.
Material Direction
Buyers do not always fix the final grade first, but they usually know the material direction they need.
Gray iron
Common for machine structures, bases, housings, and damping-oriented programs.
Ductile iron
Suitable for higher strength, toughness, pressure, and assembly-related requirements.
Cast steel
Suitable for higher-load structures and more demanding service conditions.
Wear-resistant / high-chromium
Suitable for abrasive-duty parts with clearer hardness and service-life targets.
Other metal grades
Can be reviewed further based on drawing, service conditions, and machining needs.
Typical Parts
These part families help buyers judge quickly whether the factory already supports similar projects.
Support Scope
Many projects depend on whether the downstream support is organized well enough to land the program.
RFQ Start
For most projects, sending the drawing package first is more effective than waiting until every detail is fully fixed.
FAQ
短い回答により、能力範囲とRFQ導線を理解しやすくします。
Can a buyer send the drawing before the final material grade is fixed?
Yes. If the application, part structure, and approximate material direction are already known, the first technical review can usually start.
Does Hongsen only cast parts, or also support machining?
Hongsen supports casting, CNC machining coordination, inspection, and export delivery for drawing-based OEM projects.
Which project types are a good fit for drawing-first RFQs?
Pump, valve, housing, machine tool, agricultural machinery, industrial machinery, and wear-part projects are all good candidates when material, process, and machining need to be reviewed together.
