Welding Fabrication

Miniature refrigerated gourmet delicatessen showcase
●Demand Accuracy: ±0.05mm
●Material Type: SUS304
●Thickness: 1.5mm

This is a miniature of our entry "refrigerated gourmet delicatessen showcase". Our customers, high-grade delicatessens and pastry shops, demand showcases of high quality to enhance the value of their products. Especially, stainless steel exterior finishing accentuates minute finishing defects and calls for advanced welding skills.
The semisphere is composed of eight parts drawn with simple urethane rubber tools. The top, side and bottom parts are welded together closed without relief.
Key points in fabrication are the accuracy of connected surfaces and the skill of welding to control thermal deformation. Welding heat-induced torsion is prevented and deformation-free finishing is achieved. The actual product is ten times larger and is composed of spherical glass panels. Aesthetics must be combined with high accuracy. We think it was the driving force for our award.
We fabricated this award-winning product in a single try by a process similar to the one we use to make our ordinary products. We were surprised to receive Nikkan Kogyo Shimbun Award and Gold Award and at the same time, were glad to know that our business-as-usual way of making things was recognized. We intend to improve our techniques and aim to make products that demonstrate the skill and heart of our employees.
