Custom Metal and Plastic Parts Manufacturer in China. 

YS Precision is a professional custom metal and plastic parts manufacturer in China, providing CNC machining, injection molding and integrated manufacturing services for customers worldwide.

Our production capacity is supported by more than 100 machines. This includes nearly 50 five-axis CNC machining centers, 36 CNC lathes, four Swiss-type CNC machines, two turn-mill machining centers and more than 10 injection molding machines.

This equipment, combined with our experience in mold tooling, sheet metal fabrication, casting, rapid prototyping and surface finishing, enables us to support projects from early prototypes and small batches to volume production.

We manufacture non-standard components according to customers’ 2D drawings, 3D models and technical specifications. Whether the requirement is an individual precision part, a molded plastic component or a project involving multiple manufacturing processes, our focus is on practical production planning, consistent quality and dependable delivery.

Custom Parts Made to Your Drawings

We manufacture components developed for specific products, machinery and equipment rather than standard catalogue parts.

Our work mainly includes:

• Custom CNC machined metal and plastic parts
• Precision milled and turned components
• Complex five-axis machined parts
• Prototypes and production parts
• Custom injection-molded parts
• Sheet metal and cast components

Each project begins with a review of the design, material, tolerances, surface finish, quantity and intended application. Based on these requirements, we select an appropriate manufacturing process and plan the necessary production, inspection and finishing operations.

This project-specific approach allows us to support parts with different geometries, materials and technical requirements while selecting a suitable process for each component.

CNC Machining and Injection Molding Capacity

CNC Machining Capacity

CNC machining is one of our core manufacturing capabilities.

Five-axis CNC machining supports components with complex geometries, multiple machined surfaces and difficult-to-reach features. CNC lathes provide efficient production for round and rotational components, while Swiss-type and turn-mill machines are well suited to smaller, detailed parts requiring several machining operations.

We machine a broad range of metals and engineering plastics, including aluminum, stainless steel, steel, brass, copper, titanium, ABS, PC, POM, PA, PMMA, PEEK, PEI and PTFE.

Injection Molding Capacity

Our injection molding equipment supports mold trials, initial production runs and volume manufacturing of custom plastic parts. Each molding project is evaluated according to the part design, material, tooling requirements, appearance standards, expected quantity and assembly needs.

With different types of equipment available, we can allocate suitable machines according to part geometry, material, tolerances and order quantity. This provides flexibility for individual prototypes, parallel production of multiple components and ongoing batch production.

Equipment capacity provides the production foundation. Process planning, machine selection, tooling, scheduling, in-process control and project follow-up help turn that capacity into consistent parts and reliable delivery.

From Prototypes to Volume Production

Our manufacturing services support customers at different stages of product development.

Early prototypes may be used to evaluate dimensions, appearance, assembly, material performance or function. Depending on the project, they can be produced through CNC machining, 3D printing, urethane casting, sheet metal fabrication or prototype injection molding.

After the design has been tested and approved, the project can progress to small-batch manufacturing, bridge production or volume production.

The most suitable process may change as quantities increase. CNC machining may remain appropriate for precision parts and flexible batch production, while injection molding, die casting or other tooling-based processes may become more economical at higher quantities.

We consider the part design, material, tooling investment, required quantity, production efficiency and anticipated demand when helping customers move from prototypes to production parts.

This allows customers to begin with the quantity they currently need while maintaining a practical path toward larger-scale production.

Integrated Manufacturing Capabilities

Many products contain components that require different materials and manufacturing processes. In addition to CNC machining and injection molding, our capabilities include:

• Rapid prototyping
• Silicone compression molding
• Sheet metal fabrication
• Aluminum and zinc die casting
• Investment casting with secondary CNC machining
• Surface finishing and product marking
• Fit checking, light assembly and packaging

Not every component should follow the same manufacturing route. We evaluate each part individually and select a process suited to its structure, material, tolerances, surface finish and production quantity.

For projects involving multiple components or processes, our Integrated Manufacturing Solutions bring production, inspection, finishing and delivery together under one coordinated project plan.

This gives customers one point of contact for related machined, molded, fabricated and cast parts.

Technical Review and Quality Control

Reliable manufacturing begins before machining or mold production starts.

We review customers’ 2D drawings, 3D models and technical specifications to confirm the material, drawing revision, critical dimensions, tolerances, surface finish, quantity and assembly requirements.

If a feature may affect machining, molding, finishing or part fit, we discuss it with the customer before production whenever possible. Identifying potential issues early helps reduce unnecessary revisions and keeps production moving according to plan.

Our quality management system is certified to ISO 9001:2015. Quality checks are arranged according to the drawing, part geometry and manufacturing process and may include:

• Incoming material confirmation
• First-piece inspection
• In-process dimensional checks
• Final dimensional and visual inspection
• Thread, hole and mating-feature checks
• Surface finish and color inspection
• Fit checks for related components
• Inspection records when agreed before production

Quality is monitored at appropriate production stages rather than checked only after all operations have been completed. For components involving several processes or secondary surface treatments, inspection points can be arranged between operations when necessary.

Our objective is to ensure that completed parts conform to the approved drawings and agreed technical requirements.

Industries We Support

Our manufacturing capabilities support custom parts for a broad range of industries, including:

• Aerospace
• Robotics
• Automotive and transportation
• Medical and diagnostic equipment
• Automation and industrial equipment
• Laboratory and optical equipment
• Semiconductor equipment
• Electronics and communications
• Consumer products and home appliances
• Energy and marine equipment
• Agricultural and livestock equipment

Our experience is not limited to these industries. We welcome custom prototype and production projects for different products, machinery and equipment.

Support for International Customers

Clear communication and dependable follow-up are essential when sourcing custom parts internationally.

Customers work with one point of contact throughout the project. We coordinate technical questions, drawing revisions, material preparation, production scheduling, inspection, surface finishing, packaging and shipment.

Lead times are evaluated according to the manufacturing process, material availability, quantity, finishing and inspection requirements. Our production capacity provides flexibility when scheduling different machines and processes, while active project follow-up helps keep production on track.

If an unexpected issue may affect the technical requirements or agreed schedule, we communicate it promptly and work with the customer toward a practical solution.

International shipping can be arranged by express, air or sea freight according to the order quantity, delivery schedule and packaging requirements.
