Core Business

Mold Castings

We design and produce mold castings used in automotive aluminum wheel manufacturing. Built on four decades of foundry know-how, each program balances dimensional precision with heat resistance from prototypes through mass-production tooling.

Dimensional control that minimizes secondary machining
Material engineering for heat and wear resistance
One-stop response from prototypes to production tooling

Precision Machine Castings

We manufacture high-strength cast components for industrial machinery and heavy equipment. High-frequency induction melting reduces impurities, while strict chemical and physical inspections ensure only qualified parts are released.

Clean melts powered by high-frequency induction furnaces
Verified chemistry and tensile-strength inspections
Pattern design support for complex component geometry

Custom Casting Solutions

From gray iron (FC) to ductile iron (FCD), we tailor casting programs to customer drawings and specifications. Engineering support begins at the design stage so the final part meets performance goals while staying on schedule.

Process selection optimized for FC and FCD materials
Technical consulting from the earliest design phase
Stable delivery backed by consistent quality management

Manufacturing Process

From Melt to Masterpiece

Every casting goes through our meticulous 5-step process, ensuring uncompromising quality at every stage.

Raw Material

Material Prep
Carefully selected scrap iron and alloys are prepared and inspected before melting.

Melting

Melting
High-frequency induction furnaces heat materials to 1,500°C with precise temperature control.

Molding & Pouring

Molding & Pouring
Molten iron is poured into precision sand molds, capturing every detail of the pattern.

Finishing

Finishing
Castings are cleaned, machined, and surface-treated to meet exact specifications.

Quality Control

Quality Control
Rigorous testing ensures every product meets international quality standards.
