エスティエム Company Profile

Leave the annealing of materials before press molding to us!

Our company provides "heat treatment technology" tailored to meet our customers' needs. Because heat treatment is a process that is not visible from the surface, it is essential to maintain stable properties and hardness, delivering products that our customers can trust. We will create high-quality products using the "skilled techniques" of human hands and "thorough inspections" that are verified by human eyes.
