JIN-TI's core strengths: 40 years of tool steel expertise × Japanese 5-axis equipment × automated measurement × robotic collaboration
Technology Overview
Based in Changhua, Taiwan, JIN-TI Industrial has specialized in precision tool steel machining for over 40 years. Our facility integrates the core processes in-house: CNC milling, Japanese 5-axis machining, precision wire-cut EDM, grinding, heat treatment, and PVD coating — supported by automated measurement systems and robotic production lines, covering everything from material selection to finished parts.
Operating under an ISO 9001:2015 quality management system with tolerance control at the ±0.01 mm level, we serve international customers across three verticals: sewing machines, semiconductor equipment, and medical devices. Every batch carries complete production and inspection records for full traceability.
Japanese 5-Axis CNC Machining
Our shop floor is equipped with premium Japanese 5-axis milling machines that complete multi-face machining of complex geometries in a single setup. Compared with conventional 3-axis machining that requires repeated refixturing, 5-axis machining greatly reduces cumulative positioning error, delivering more stable accuracy and consistent surface quality.
This capability is ideal for geometrically complex, tight-tolerance sewing machine mechanism parts and semiconductor equipment components. Combined with CAM program management and tool-life control, it ensures repeatability in volume production.
Automated Measurement Systems
Automated measurement runs throughout our production flow, digitizing quality data with multi-axis precision instruments and coordinate measuring machines (CMM). Results feed back to the shop floor in real time, so dimensional drift is caught before it can become a batch defect.
Critical dimensions are inspected 100% or by sampling plan according to the inspection scheme, and measurement reports can be supplied with each shipment for full visibility into batch quality.
Robotic Arm Collaboration
Robotic production lines handle repetitive operations such as loading/unloading, transfer, and grinding — stabilizing cycle times, reducing human variation, and freeing skilled operators to focus on inspection and machine setup.
Flexible line configurations mixing automation with manual work let us maintain both quality and delivery for high-mix low-volume as well as high-volume orders.
Tool Steel Machining & Heat Treatment
Four decades of tool steel experience form JIN-TI's foundation. We know the machining and heat-treatment behavior of common tool steels such as SKD11, SKD61, and high-speed steel, using quenching, tempering, and stress relieving to stabilize part dimensions and prevent deformation in service.
Where wear resistance matters, PVD coating adds surface hardness and abrasion resistance, extending the service life of high-wear components.
Vertical Integration Capabilities
From material selection, rough machining, heat treatment, and finish machining to surface treatment and final inspection, our main processes are completed in-house. Vertical integration keeps quality and lead time truly under our control — no waiting on subcontractor schedules, and immediate in-house countermeasures when issues arise.
For customers, this means shorter lead times, more consistent quality, and single-window communication.
