Copper Investment Casting: Precision Manufacturing for Kitchen Components

Shaanxi Rongbao Machinery Electronics Co., LTD delivers enterprise-grade copper investment casting solutions for kitchen applications. Our H62 brass casting process produces components weighing 0.23kg with exceptional dimensional accuracy and surface quality. With ISO 9001:2015, ISO 14001, and ISO 45001 certifications, we maintain rigorous quality control throughout production. Our facility achieves production capacity of 5,000 pieces for customized specifications, supported by CNC machining and shot blasting surface treatment. Backed by 14 utility model patents and National High-Tech Enterprise status, we export 70% of products to the United States, Europe, and Japan.

Why Choose Our Copper Investment Casting Service?

You need manufacturing partners you can trust to know accuracy needs. Our gravity cast process produces copper alloys with very low porosity and uniform wall thickness.

All parts are CNC machined to exacting specifications. Shot blasting process produces a uniform surface finish and enhances adhesion qualities.

We adapt specifications to your technical drawings or 3D models. This versatility enables you to fulfil your particular design requirements without compromising quality standards.

Technical Specifications

Manufacturing Process Overview

Mould Design & Development

Your project begins with an in-depth mould design evaluation. We consider structural feasibility and suggest process optimisation.

Our engineering team builds moulds in 15 to 25 days. Including dimensions validation and trial casting evaluation.

Gravity Casting Production 

The prepared moulds are filled with molten H62 brass under controlled conditions. Gravity casting has less inclusion of oxide and zero turbulence.

This approach has better mechanical qualities compared to high pressure procedures. This leaves you with components that have superb metallurgical integrity.

Precision Manufacturing

CNC machinery processes castings to finished sizes. We meet the close tolerances necessary for functioning kitchen hardware.

Multi-axis machining centers are well suited to complicated geometries. The quality check was carried out as per standard measuring techniques.

Surface Finishing

Shotblasting removes scale and produces a consistent surface texture. This preparation improves both the look and the way it works.

Our treatment technique complies with international norms of kitchen equipment. You get parts ready for assembly or further finishing.

Quality Assurance Standards

We do complete quality management in production cycles. Our methodical approach to quality control is confirmed by ISO 9001:2015 accreditation.

Dimensional inspection is done with calibrated measurement equipment. Metallurgical testing validates that the material composition and mechanical properties are within standards.

ISO 14001 certification proves your environmental responsibilities. We manufacture in ways that generate less waste and control emissions well.

Our production staff is protected by ISO 45001 occupational safety regulations. Safe operations mean constant product quality for your supply chain.

Customization Capabilities

OEM and ODM Services

Submit your technical drawings or concept designs. We provide design-for-manufacturing feedback to optimize casting feasibility.

Our ODM service includes engineering consultation. You benefit from our 20+ years of casting expertise during product development.

Flexible Specifications

Every dimension can be customized to your requirements. We accommodate various weight ranges and complexity levels in copper investment casting projects.

Material selection extends beyond H62 brass. Consult our technical team regarding alternative copper alloys for specific applications.

Application-Specific Solutions

Kitchen components demand food-safe materials and corrosion resistance. Our H62 brass composition provides both properties naturally.

We understand thermal conductivity requirements for cooking equipment. Copper alloy selection balances performance with manufacturing efficiency.

Global Supply Chain Experience

70% of our produce is sent to international markets With this experience you are guaranteed smooth cross-border logistics and documentation.

Our export packing is in the international standard hardwood boxes. Products are shipped secure against damage in transit.

We have passed SSBM audits from global technology companies including ABB. These assessments validate our capacity to satisfy challenging supplier criteria.

We deliver on time for our European and American customers. On-time delivery keeps your production schedules on track and free from slips.

FAQ

Q: What minimum order quantity do you require for the product?

A: Our standard MOQ is approximately 100 pieces. This quantity balances mold development costs with unit pricing for customized components.

Q: How long does production take from order confirmation?

A: Regular orders require 20–30 working days total. Mold manufacturing takes 15–25 days, followed by 7–20 days for batch production and finishing.

Q: Can you match specific copper alloy specifications?

A: Yes, we work with various copper alloys beyond H62 brass. Provide your material requirements during quotation for feasibility evaluation and recommendations.

Q: What quality certifications apply to kitchen components?

A: Our ISO 9001:2015, ISO 14001, and ISO 45001 certifications cover manufacturing processes. For market-specific certifications like CE, please discuss requirements with our sales team.

Q: Do you provide design assistance for casting optimization?

A: Absolutely. Our engineering team reviews designs for casting feasibility and suggests modifications to improve quality, reduce costs, or simplify production.

Q: What surface finishes are available besides shot blasting?

A: We offer multiple surface treatment options depending on your aesthetic and functional requirements. Contact us to discuss polishing, coating, or plating alternatives.
