キャステム Company Profile

A convenient company with unique technology! 'Castem' specializing in laser welding processing.

The company was established to promote the mass production of zinc alloy molds. We have received many adoptions in various fields, including the first-generation hybrid vehicle bumpers, automotive, office automation, home appliances, and daily necessities. As the external environment has changed significantly, since 2006, we have contributed to the mold industry as a company that introduced laser welding machines and performed buildup repairs on molds. In recent years, based on the welding technology we have cultivated, we are striving to expand our sales channels to a wide range of industries and meet diverse needs as a manufacturer specializing in laser welding processing. Additionally, we assist our customers in technological innovation through new businesses such as test prototyping and research and development support.

Business Activities

【Business Description】 ● Laser Welding Processing "Mold repair, buildup welding, joining" "Testing, prototyping, contract research and development" 【Technology】 ● Advanced welding technology: specialized techniques ● Dissimilar metal joining (toughness and hardness, multi-materials, weight reduction) ● Ultra-fine welding (buildup, joining)

Recommended information

Laser welding processing: "Mold buildup" "Unique joining technology"

Laser welding processing: "Mold buildup" "Unique joining technology"

We offer a wide range of services related to welding, from laser mold repair and various joining technologies to "testing and prototyping" contract services. [Various case studies available]

【Advanced Build-Up Technology for Molds】 - Fine shapes such as connectors and semiconductor encapsulation molds (build-up diameter 50µm, approach dimension 10µm: the smallest in the industry) - Narrow and deep areas such as rib shapes and gate openings (numerous requests from across the country) - Diverse proposals tailored for welding purposes such as cracks and erosion (including other reinforcement, nitriding, and texture countermeasures) 【Dissimilar Metal Joining & Multi-Material】 Joining various practical metals such as Fe, aluminum, SUS, titanium, copper, brass, and nickel using laser technology Multiple instances of base material fracture depending on conditions 【Fine Joining】 Joining of sheets and pipes from 10µm and above. Please consult us regarding materials and shapes 【Test Processing Contract】 - Prototype and test processing contracts from single items to small lots - Contracting for research and development with no prior examples. Support from feasibility judgment to quality stabilization to mass production *For more details, various case studies are published in the related links.*
