Casting route
Lost foam, clay sand, resin sand, coated sand, or other routes can be reviewed based on geometry, batch demand, and project risk.
Manufacturing Capability
The manufacturing chain covers smelting, multiple casting workshops, machining, spraying, inspection, packing and export delivery preparation for metal casting projects.

Capability Quick Reference
This page explains how Hongsen connects drawing review, casting-route selection, machining, inspection, and export coordination instead of showing isolated equipment only.
Casting route
Lost foam, clay sand, resin sand, coated sand, or other routes can be reviewed based on geometry, batch demand, and project risk.
Supporting scope
After casting, machining faces, holes, datums, inspection items, packing, and delivery can be reviewed together.
Engineering support
Complex geometry or prototype discussion can include large-format metal additive manufacturing support when useful.

Capability Scope
Production follows a connected chain: process selection from the drawing, matching the right casting line, machining critical surfaces, coordinating finishing and preparing the order for export delivery.
Custom casting route evaluation based on customer drawings, samples and technical specifications
Automated smelting resources including batching, oxygen-enriched coal injection and controlled furnace operation
Multiple casting routes covering lost foam, resin sand, coated sand, iron-based coated sand and precision casting
Large-format metal additive manufacturing support for complex structure review and prototype discussion
Five large-scale casting rooms and three machining rooms
Gantry machining, CNC processing, spraying and downstream finishing coordination for cast metal parts
Inspection planning, packing protection and export delivery preparation for overseas OEM orders
Factory Visual
The brochure already shows blast furnace, sintering, oxygen-enriched, and power-generation support equipment. These real workshop visuals make the capability section more convincing than generic factory photos.

Metal Additive Manufacturing Support
Large-format metal 3D printing is presented as a supporting engineering capability for drawing-based casting projects. It helps buyers discuss complex geometry, prototype verification, process-risk points and later casting-plus-machining coordination before the project is fixed.
Complex structure review: useful when a 3D model includes internal passages, difficult wall transitions or areas that may affect casting route selection.
Prototype and pilot-batch discussion: helps the project team compare design intent, manufacturability and early validation needs before stable batch production.
Casting and machining coordination: connects additive review with casting route, machining allowance, distortion risk, inspection focus and export delivery planning.
No unverified equipment parameters are used here. The value is shown through how the capability supports real casting review.
Workshop Flow
These workshop visuals show that custom metal casting projects move through multiple linked production areas.

Factory Visual
Used for medium and large castings across varied industrial programs.

Factory Visual
Used for castings that need stable dimensions and cleaner surface presentation.

Factory Visual
Downstream finishing stage before packing for export.
RFQ Focus
Send the drawing with tolerance, machining and finish requirements so the project can be reviewed against casting route, machining scope, inspection flow and delivery preparation.
