Sheet Metal Fabrication

Sheet metal fabrication is a method where sheet metal parts and assemblies are formed by bending, forming, cutting, punching, or stamping a metal sheet, which is a subtractive manufacturing process that forms parts from thin metal sheets. Engineers often choose sheet metal parts for their high precision and durability, especially for end-use applications like chassis, enclosures, and brackets. View More+

Our goal is to provide customers with full-service solutions. View More+

In-House Electropolishing

Electropolishing is an electrochemical process that provides a variety of benefits, including deburring, micro finish improvement, and improved corrosion resistance by eliminating embedded contaminants and surface imperfections. Jinyuan provides in-house Electropolishing & Passivation services for various applications in the semiconductor and medical industries. ​We have solutions that can handle standard grade (304, 316) stainless steel.Our staff is highly skilled and experienced in providing stainless steel solutions. They have the necessary training and expertise to give a fantastic result. View More+

Ultrasonic Cleaning

Ultrasonic cleaning uses high frequency sounds waves, those beyond the range of normal human hearing (18 kHz), and an appropriate cleaning solvent to remove contaminants from parts.The ultrasound can be used with just water or be combined with surfactants to gently remove residual cutting oils and microscopic chips.

Microscopic Deburring

In the manufacturing world, deburring refers to various methods used to remove burrs, the residual rough edges or protrusions left behind after a part is produced. Surface roughness and edge quality play an important role in the overall manufacturing process. Having control of burrs in the final stages will help promote adhesion or cosmetic finishes, reduce negative product performance, and improve general surface appearance. View More+


Over the years, Jinyuan has established a network of proven suppliers in Asia. We work closely with platers and surface coaters to ensure that your components are processed to exacting plating and finishing specifications, adhering to MIL specs and ROHS/NADCAP-approved sources. After outside plating processing, your parts go through a final visual and dimensional inspection. View More+

Precision Grinding

Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained.We can perform Centerless Grinding services for the large number of metal parts you may want grinded within a short period of time. Centerless Grinding is definitely the way to go if you have a large number of parts and components that need to be shaped and grinded. We offer high precision Thrufeed and Infeed centerless grinding for workpieces. View More+
