About Bronze Casting Service
Comprehensive Bronze Casting Process Options
Lost-Wax Casting (Investment Casting)
Lost-wax casting is the best standard for producing bronze parts with complex internal and external structures, fine details, and exceptional surface finish.
Advantages:
Extremely high precision
High design freedom
Excellent surface finish
Applications: Complex impellers, artistic sculptures, precision instrument housings, valves, and pump bodies.
Our Solution: We possess mature lost-wax casting technology and a quality control system. We can manage the entire lost-wax casting process for you and utilize our in-house ultra-precision machining capabilities to complete the final finishing, ensuring the final product meets the highest standards.
Sand Casting
Sand Casting is the most suitable option when your parts are large, have a relatively simple structure, or are cost-sensitive. We have a significant advantage in this field thanks to our robust production facilities.
Advantages:
High cost-effectiveness
Wide size range
High material adaptability
Applications: Large gear blanks, ship propellers, machine frames, pump housings, large bushings.
Lost Foam Casting
This process combines some of the advantages of sand casting and lost-wax casting, and is particularly adept at manufacturing parts with complex internal channels and structures.
Advantages:
One-piece molding
Good precision
Simplified process
Applicable scenarios: Complex engine blocks, manifolds, valve bodies, and pump bodies.

Our "Casting+" Integrated Capabilities
Choose us, and you get more than just castings. We add decisive value to your projects through our powerful in-house finishing capabilities.
A leap from 1mm to 0.002mm
The standard tolerance for casting blanks is 1mm, but after machining on our vertical/horizontal machining centers, Seibu wire EDM, and precision grinding machines, the final part accuracy can reach 0.002mm.
ISO Grade 5 Gear Manufacturing
We can directly machine high-precision gear profiles to ISO Grade 5 accuracy onto your bronze castings (such as worm gear blanks).
One-stop Quality Control
From casting to final inspection, all stages are completed under the monitoring of our quality system, ensuring the reliability and consistency of the final product.

Our Process Flow
Technical Consultation & Design
Our engineers will communicate in depth with you, analyze drawings, and recommend the best material and process solutions based on your application requirements.
Mold Design & Manufacturing
Utilizing advanced CNC automated mold-making equipment, we manufacture high-precision molds, which is the first step in ensuring the quality of the final casting.
Melting & Pouring
We strictly adhere to material grade standards when melting bronze alloys and pour them under precise temperature control to ensure a uniform internal structure in the casting.
Post-Processing & Cleaning
After the casting cools, we perform sand removal, cut the risers and gating gates, and sandblasting or shot blasting to obtain a clean casting blank.
Precision Machining
The casting blank is transferred to our machining center, where top-of-the-line equipment such as the Kashifuji KPS30, Seibu WEDM, and Brother TC-S2A performs final dimensional and positional precision machining.
Quality Inspection
100% full-dimensional inspection of the final product is conducted using precision equipment such as a coordinate measuring machine (CMM) and gear measuring instrument, and a detailed quality inspection report is available.
Packaging & Delivery
Secure, shockproof, and rustproof packaging is used to ensure the product arrives intact during transportation and is delivered on time.
Application Areas
Heavy Machinery and Equipment: Wear-resistant worm gears, bushings, bearings, and slide blocks.
Marine and Marine Engineering: Seawater-resistant propellers, valves, pump bodies, and pipe fittings.
Automotive and Transportation: High-strength synchronizer rings, bushings, and connectors.
Aerospace: Lightweight, high-strength bushings and supports for landing gear systems and actuators.
Valves and Fluid Control: Complex valve bodies, seats, and sealing rings.
