キャステム Company Profile

A lost-wax precision casting company with 55 years of experience. With technology that has been elevated by "half a step," we empower the people who create things.

With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. In 1991, we obtained a U.S. patent for "MIM (Metal Injection Molding)." Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We provide optimal proposals through various technologies! We thoroughly support our customers' manufacturing processes! We specialize in complex three-dimensional shapes in small lots of various types and carry out everything from mold making to casting, machining, and simple assembly in-house. We supply products to various industries, including medical devices, semiconductors, machine tools, and aerospace. "Just make it, from one piece." We can propose a wide range of manufacturing methods from prototype production of one piece to mass production. We enable time savings in searching for various suppliers and considering consultation destinations, becoming a true total cost reduction partner by proposing reductions in management costs associated with consideration time and product costs. More than half a century ago, Castem's casting began with handmade machine tools. Today, we have become a company with the top domestic share in the manufacturing of general industrial parts using lost wax and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.

モノづくりフェア2026 出展案内.jpg

Don't give up just because it's a small quantity! We can handle everything from a single cast part to mass production. Castem will exhibit at the Monozukuri Fair 2026.

  • NEW
  • COMPANY

Castem Co., Ltd. will exhibit at the "Monozukuri Fair 2026" held at Marine Messe Fukuoka from October 14 (Wednesday) to 16 (Friday), 2026. "Small lots are not suitable for casting" and "You can't make a casting with just one piece" — Have you given up on producing cast parts for such reasons? At this exhibition, we will introduce three casting methods that can be selected according to application and quantity, as well as MIM (Metal Injection Molding) suitable for fine and thin-walled parts. We will propose the optimal manufacturing method tailored to your needs, from prototyping and development of metal parts to small-lot production and mass production. We welcome inquiries such as "Can this part be cast?" and "Can you accommodate small quantities?" In addition to samples of each method, we will also display a dragon sculpture that poses a high casting difficulty. You can experience Castem's technological capabilities on-site. Please visit the Castem booth. 【Exhibition Overview】 Exhibition Name: Monozukuri Fair 2026 Date: October 14 (Wednesday) to 16 (Friday), 2026, 10:00 AM to 5:00 PM (until 4:00 PM on the last day) Venue: Marine Messe Fukuoka Hall A (7-1 Okihama-machi, Hakata-ku, Fukuoka City, Fukuoka Prefecture) Exhibition Booth Number: AE-38
