OEM Overview:

Custom OEM Manufacturing Support

We provide build-to-print OEM manufacturing services for customers who require custom metal and plastic parts. Based on your drawings, 3D models, samples, material requirements, and quality specifications, we organize the appropriate manufacturing process and deliver parts ready for your application or assembly.

Our OEM support covers prototypes, low-volume orders, and repeat production. We work with customers across industrial automation, robotics, electronics, medical equipment, optical systems, energy, automotive, and consumer product applications.

How We Support Your Project

Manufacturing based on customer drawings and technical specifications
Material, surface finish, and process recommendations
Prototype development and production scaling support
Custom labeling, protective packaging, and shipment coordination
Confidential handling of drawings and project information

For ODM projects, we can provide manufacturability feedback and production-oriented engineering support. Final product design ownership and technical approval remain with the customer unless otherwise agreed.

Production Line:

Integrated Precision Manufacturing

Our production line supports custom CNC machining and sheet metal fabrication for prototype, low-volume, and repeat production projects. We combine CNC machining centers, CNC lathes, Swiss-type turning, 5-axis machining, grinding, EDM, laser cutting, bending, finishing, and assembly resources to manufacture parts according to customer drawings and specifications.

Our production process is managed from material preparation and machining through inspection, surface finishing, packaging, and shipment. We focus on stable processes, clear production coordination, and careful control of critical requirements.

Core Manufacturing Processes

CNC milling, CNC turning, 5-axis machining, and Swiss-type turning
Grinding, wire EDM, and precision secondary operations
Laser cutting, sheet metal bending, welding, and fabrication
Surface finishing, hardware installation, and assembly
Final inspection, protective packaging, and export delivery

Our flexible production resources allow us to support a wide range of custom parts, from simple turned components to complex precision assemblies.

R&D:

Engineering and Manufacturing Development Support

Our engineering support focuses on making custom parts practical to manufacture, inspect, and deliver. We review drawings, tolerances, materials, finishes, and production requirements before manufacturing begins, helping customers identify potential manufacturability concerns at an early stage.

For new product development and prototype projects, we support the transition from concept to production-ready components through process planning, sample manufacturing, and continuous communication. Our goal is to help reduce avoidable production risk while maintaining the functional requirements of your design.

Engineering Support Includes

Drawing and 3D model review
Design for Manufacturability feedback
Material and surface finish suggestions
Tolerance and process feasibility evaluation
Prototype sample support and production planning
Inspection planning for critical dimensions

We work as a manufacturing partner for engineering teams that need reliable feedback, responsive communication, and practical support from prototype through repeat production.

Our Team:

A Team Focused on Manufacturing Execution

At ChenRong, our team combines manufacturing knowledge, production coordination, quality awareness, and export service experience. We understand that custom parts require more than machine time—they require accurate communication, careful process control, and reliable follow-through.

Sales and Project Coordination

Our customer-facing team supports quotation, drawing review, project communication, production follow-up, and delivery coordination. We work to make technical communication clear and efficient for overseas customers.

Engineering and Production

Our engineering and production personnel focus on turning drawings and specifications into manufacturable parts. They coordinate machining processes, materials, tooling, finishing requirements, and critical dimensions to support stable production.

Quality Team

Our quality personnel monitor key requirements throughout production and conduct inspections before shipment. We focus on dimensional accuracy, appearance, material traceability where required, and packaging protection.

Our Working Principles

Clear and timely communication
Respect for customer drawings and confidential information
Attention to critical dimensions and functional requirements
Practical problem-solving before production begins
Continuous improvement in quality, efficiency, and service

We work as an extension of our customers’ supply chains, helping transform concepts and drawings into production-ready parts.

History:

Our Story

ChenRong was established to provide a more responsive and practical custom manufacturing service for global customers. Our foundation is built on hands-on experience in precision metal fabrication, CNC machining, production coordination, and international B2B communication.

We began with a clear objective: to help customers source custom parts with less uncertainty. Many buyers face common challenges when working with overseas suppliers, including unclear technical communication, inconsistent quality, delayed responses, and limited visibility into production. Our team is committed to addressing these concerns through transparent communication, disciplined production management, and real manufacturing capability.

Built for Custom Manufacturing

Our business focuses on build-to-print manufacturing rather than standard catalog products. Every project starts with customer requirements, including drawings, materials, tolerances, finishes, quantities, and delivery expectations. This allows us to support a broad range of custom components across CNC machining and sheet metal fabrication processes.

Growing with Our Customers

As we continue to develop, we are investing in stronger manufacturing coordination, quality processes, production capability, and digital communication. Our goal is to become a dependable long-term manufacturing partner for customers who value precision, responsiveness, and continuous improvement.

We welcome opportunities to support new product development, prototype projects, repeat production, and custom manufacturing requirements from customers worldwide.
