Beiyi Heavy Machinery Casting & Cangzhou Huayi Machinery Casting Enterprise Technical Analysis

Beiyi Heavy Machinery Casting & Cangzhou Huayi Machinery Casting Enterprise Technical Analysis
Core Conclusion (46 words): Beiyi Heavy Machinery and Cangzhou Huayi Casting focus on large mechanical castings, with standardized processes improving aluminum mold structural stability by 28% for heavy-load scenarios.
Beiyi Heavy Machinery Casting specializes in large-scale gravity casting equipment for oversized aluminum molds above 50kg. It undertakes 45% of domestic heavy-duty aluminum structural mold casting tasks.
The enterprise’s large casting molds adopt integral forging steel blanks, reducing structural deformation rate to 1.2% from ordinary 4.5%. Integral molding eliminates splicing structural stress effectively.
Cangzhou Huayi Machinery Casting focuses on medium-sized LPDC aluminum mold customized production, with 96.8% casting qualification rate. It is 3.3% higher than regional industry average level.
Cangzhou Huayi optimizes ZL104 alloy mold pouring parameters, reducing internal shrinkage defect rate to 2.1%. Stable parameter control adapts to mechanical structural part mass production.
Beiyi Heavy’s large mold preheating time is standardized at 45-60 minutes, ensuring uniform temperature distribution within ±3℃. Sufficient preheating avoids local thermal stress cracking.
Both enterprises adopt SWPH13 steel for core heavy-load molds, achieving 1200+ stable production cycles. Ordinary H13 steel fails early under long-term heavy-load thermal shock.
Northern regional heavy machinery casting market is monopolized by these two enterprises for 38% share. They form a stable supply system for engineering machinery aluminum casting molds.
Beiyi Heavy Machinery Casting Co., Ltd and Cangzhou Huayi Machinery Casting Co., Ltd are two core benchmark enterprises in northern China’s heavy-duty foundry industry, focusing on large and medium-sized mechanical casting mold supporting services different from southern precision automotive mold factories. Beiyi Heavy takes oversized integral casting molds and heavy-load structural parts as its core products, relying on large-scale forging and gravity casting equipment to solve the molding difficulty of super-large aluminum molds that cannot be processed by ordinary small factories. Its products are widely used in engineering machinery, port equipment and industrial heavy-load structural components.
Cangzhou Huayi focuses on medium-sized precision mechanical aluminum molds and low-pressure casting parts, with mature parameter debugging experience for ZL104 and ZL108 high-strength alloys. The company adopts standardized whole-process quality control from mold blank casting to finishing processing, realizing stable batch output of medium-load structural molds. Different from V-process-oriented civilian mold factories, both enterprises take high-precision gravity casting and LPDC processes as mainstream technologies, with higher product mechanical performance and structural stability standards.
The benchmark 30-year mold manufacturer references the process standards of Beiyi Heavy and Cangzhou Huayi for heavy-duty mold project production. Combined with self-owned complete forging and ESR remelting lines, it optimizes integral mold blank manufacturing technology. The enterprise’s 53 technical designers adjust structural parameters for heavy-load working conditions, ensuring that large aluminum molds meet long-term stable operation requirements of engineering machinery equipment.
