YS COMPANY LIMITED company profile

YS Precision provides custom manufacturing support for prototypes, tooling, low-volume production and volume orders. Our capabilities cover precision machining, molding, casting, sheet metal fabrication and surface finishing, allowing us to support both individual parts and projects containing components with different materials and production requirements.

Our production capabilities are built around custom parts made to customer drawings, CAD data, samples and technical specifications. The manufacturing route is selected according to the part design, material, tolerance, quantity and stage of product development.

Depending on the project, we can coordinate:

• CNC milling, CNC turning and plastic CNC machining
• Five-axis CNC machining for complex, multi-sided components
• Swiss-type and turn-mill machining for precision turned parts
• CNC prototyping, 3D printing and vacuum casting
• Injection mold tooling, injection molding and silicone compression molding
• Sheet metal fabrication, aluminum and zinc die casting, and investment casting
• Anodizing, plating, passivation, painting, powder coating, polishing and marking
• Inspection, fit checking, light assembly and custom packaging

Not every part should follow the same production route. A complex housing may require multi-axis milling and cosmetic anodizing, while a small shaft may be better suited to Swiss-type turning. For plastic prototypes, CNC machining, 3D printing or vacuum casting may each be appropriate under different material, quantity and testing requirements.

Our team reviews these factors before production and coordinates the processes required for the complete part rather than treating machining, finishing and inspection as unrelated steps.

Common metals include aluminum 6061, 6082 and 7075; stainless steel 303, 304 and 316; carbon and alloy steels; brass; copper; titanium; and die-casting alloys such as ADC12 and Zamak.

Engineering plastics include ABS, PC, PMMA, POM, PA, PP, PEEK, PEI and PTFE, together with other application-specific grades. Material selection is based on the drawing and functional requirements, including strength, wear resistance, operating temperature, chemical exposure, appearance and dimensional stability.

We manufacture components for automation equipment, robotics, medical and laboratory equipment, optical systems, semiconductor equipment, automotive products, consumer electronics and industrial machinery. These are examples rather than limits; each enquiry is evaluated according to its own technical and production requirements.

For OEM projects, YS Precision manufactures custom parts according to customer-controlled 2D drawings, 3D CAD files, material specifications, tolerance requirements and finish standards. Support can begin with a prototype and continue through tooling, bridge production and ongoing volume manufacturing.

Customers retain control of their product design and technical requirements. Our role is to translate those requirements into a practical production plan, identify manufacturing risks and coordinate the processes needed to complete the parts consistently.

For projects containing several different components, one project team can coordinate machining, molding, casting, sheet metal work and surface finishing. This reduces the need to manage a separate supplier for every part and makes it easier to control revisions, fit, appearance and delivery across the project.

Our ODM support focuses on manufacturing development rather than complete product design. When a customer provides a concept, physical sample or preliminary specification, we can help develop the part toward a practical manufacturing solution.

This may include process recommendations, material selection, manufacturability improvements and prototype production for evaluation. Features that are difficult to machine, mold or inspect can be reviewed before tooling or production begins.

We do not introduce design changes without customer review. Any proposed adjustment is communicated for approval so that the intended function, appearance and assembly relationships remain under the customer's control.

Our R&D and engineering support is centered on manufacturability. Before material is ordered or tooling begins, we review the available drawings, CAD files, samples and assembly information to identify issues that could affect cost, quality, lead time or production repeatability.

The review may cover:

• Manufacturing process and setup planning
• Material suitability and availability
• Tolerance, datum and mating-part relationships
• Tool access, internal corners and deep features
• Wall thickness, draft and undercuts in molded parts
• Workholding and deformation risks
• Surface-finish requirements and protected areas
• Threads, inserts and assembly features
• Inspection methods and critical dimensions
• Opportunities to simplify production without changing part function

The purpose is not to change a design for manufacturing convenience. It is to identify avoidable risks while revisions are still easier and less costly to make.

Prototype production allows customers to evaluate fit, assembly, appearance and function before committing to tooling or a larger order. Feedback from testing can then be incorporated into the next design revision or production plan.

When several mating components are produced together, we can also perform fit checks or light trial assembly before shipment. This does not replace the customer's final product validation, but it can identify obvious interface problems and reduce avoidable rework.

For repeat and volume production, feedback from machining, molding, inspection and assembly can be used to improve workholding, process stability, cycle time and consistency between batches.
