Wing Co., Ltd.

We are a resin product manufacturer that takes pride in its machining and bonding capabilities. 

Our main line of business is the production of resin products. We manufacture parts for products including semiconductor production equipment and medical device inspection equipment. We conduct integrated machining, bonding, bending, and welding for these products. We support machining production with high-precision fine processors and large five-axis machining tools with related technologies. These allow us to handle products from small grain-size articles to large 2500 × 2500 cleaning tanks. We also possess technology for highly transparent bonding with fewer bubbles, and we have skilled welding engineers to provide high-precision processing. These services are highly evaluated in all aspects of QCD (quality, cost, and delivery) by major manufacturers in the fields of semiconductor and liquid crystal production equipment.

[Company strength]
We can offer high-precision machining that makes use of our high-precision fine processors and large five-axis machine tools. We can handle any size from grain-sized articles to large 2500 × 2500 cleaning tanks. Our inspection equipment includes CNC three-dimensional measuring machines and CNC image measuring instruments, and we have an established quality control system in place. Our management framework also includes own production control system and quality control manuals, which allowed us to obtain Eco Action 21 certification. 

[Business description]
Our company provides advanced high-precision machining, bonding, bending, and welding technologies with high reliability and quality control as our guiding principles. We focus on resin products to meet a wide range of user needs. Our main business involves the production of welding compound products (such as resin chambers for semiconductor production equipment and liquid crystal production equipment). It also involves high-precision machine products (such as parts for medical devices, semiconductor inspection equipment, and optical devices), and machining tools and jigs for automobile plants and electric appliance plants. 

Plastic processing

[Strength of products/technologies]
Our company conducts all processes such as machining, welding, assembly, and other processing, so products are finished with high precision. In plastic bending processing we can handle thick plates and polycarbonate materials. A characteristic of our bonding is that it contains fewer air bubbles, which makes the bonded part very transparent. Welding is manually conducted by experienced engineers who make use of their accumulated skills to create a smooth finish. Our resin machining equipment includes both a 5-axis CNC router for 3D machining of large products, and high-speed, high-precision fine processors for curved surface processing for small, lens-sized products. Our sound manufacturing practice has been highly evaluated by our customers. Three of our welders hold Japan Welding Engineering Society certification, and their skills are being transferred within the organization.

[Representative's message]
Our company was established in December 1999. Since then we have been providing resin welded parts and precision machined parts for use in ever-more-sophisticated electronic parts production equipment. The customer trust we have won along the way has enabled steady growth for our company. Our customer base has also grown in many fields, including semiconductors, liquid crystals, healthcare, automobiles, agriculture, and marine products. We will continue to advance our technology to meet new customer needs, and strive to become an indispensable company as we contribute to society by constantly supplying high-quality products. Technology proposals and advances for market cultivation are part of this policy, and we will pursue them even more vigorously in the future. 

[Company structure for market development/overseas expansion]
Please consult us if you have concerns over regulations applied to imported products, such as the RoHS Directive and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals). We can come up with alternative materials or other responses. We recently participated in MEDTEC Japan 2015 and other business meetings, and launched a company website as part of our market cultivation efforts. Overseas expansion is an important topic for us, and we hope to extensively expand our markets through J-GoodTech.

[Market share/Ranking]
Our company has earned high evaluations from major manufacturers in the fields of semiconductor and liquid crystal production equipment, and we have received commendations for excellence in QCD.
