Custom Investment Casting & CNC Machining Solutions for Hardware Components

Hardware casting parts are widely used in industrial hardware, construction hardware, mechanical fasteners, connectors, and structural accessories, where dimensional consistency, mechanical strength, surface quality, and cost efficiency are essential.

These components are typically manufactured through investment casting combined with precision CNC machining to achieve accurate dimensions, clean surface finish, and reliable assembly performance in hardware OEM projects.

At Foshan Zeren Precision Casting Co., Ltd., we specialize in custom OEM hardware casting parts, providing one-stop investment casting and CNC machining services based on customer drawings and technical specifications.

With over 15 years of experience in silica sol investment casting, we manufacture a wide range of hardware components using stainless steel, carbon steel, and alloy steel, ensuring stable quality, consistent dimensions, and competitive cost for large-volume production.

Custom Investment Casting for Hardware Casting Parts (OEM & Non-Standard)

We use advanced silica sol lost wax investment casting technology to produce custom hardware casting parts with complex geometries, consistent wall thickness, and tight dimensional tolerances.

This process is especially suitable for non-standard OEM hardware casting parts that require stable quality, repeatability, and cost-effective manufacturing for medium to large production volumes.

Key Advantages of Our Investment Casting Process

· Suitable for complex and thin-wall instrument casting designs

· Excellent surface finish (up to Ra 3.2 μm)

· Tight dimensional tolerances with high repeatability

· Reduced machining allowance and material waste

· Stable quality for medium and large batch production

These advantages make our investment casting process ideal for hardware casting parts that require consistent dimensions and reliable performance.

Precision CNC Machining for Hardware Casting Components

To meet strict requirements for thread accuracy, flatness, hole position, and assembly compatibility, we provide in-house precision CNC machining services for hardware casting parts and components.

By integrating casting and machining in one facility, we ensure better dimensional control, faster lead times, and reduced manufacturing costs for OEM hardware projects.

Our CNC Machining Capabilities

· CNC milling

· CNC turning

· CNC lathe machining

· EDM machining

Our machining services support both prototype development and mass production of custom hardware casting parts with consistent accuracy and surface quality.

Heat Treatment Solutions for Hardware Casting Parts

Hardware casting parts often require specific mechanical properties such as strength, hardness, and wear resistance depending on application. We offer comprehensive heat treatment solutions to enhance performance and durability.
