Frequently Asked Questions for Tokyo Sourcing Teams
Comprehensive engineering and commercial answers addressing precision tolerances, lead times, customization, and metallurgical grade selection.
1 What makes APEX tungsten carbide circular blades suitable for high-speed Japanese slitting lines?
Our circular blades are produced using submicron 0.4–0.6 μm virgin tungsten carbide powders, followed by 10 MPa overpressure sinter-HIP. This results in zero internal microporosity and an ultra-fine grain matrix with transverse rupture strength (TRS) exceeding 3,800–4,200 MPa. When mirror-lapped to Ra < 0.02 μm, the blades offer extraordinary edge toughness, preventing micro-chipping even at speeds over 120 m/min on lithium battery electrode foils and multi-layered flexible printed circuits.
2 Can you manufacture custom circular saw blades and slitter discs according to Japanese JIS drawings?
Yes. Over 45% of our production consists of OEM/ODM custom products built strictly to customer CAD drawings (DXF, DWG, STEP) or physical samples. We routinely achieve outer diameter tolerances of ±0.005 mm, inner bore tolerances to H6/H7 (±0.003 mm), and axial thickness parallelism within 0.002 mm. Specialized keyways, pinholes, dual-bevel profiles, and scalloped edges are readily manufactured.
3 What are your typical shipping lead times to Tokyo, Yokohama, and the surrounding Kanto region?
For standard inventory sizes (such as regular rod blanks, popular slotting saws, and standard slitter discs), dispatch occurs within 24 to 48 hours. Air freight shipments to Haneda (HND) or Narita (NRT) take approximately 3 to 5 business days door-to-door. For custom drawing-based production batches requiring specialized pressing dies and PVD coatings, production lead time averages 12 to 18 working days, followed by air or direct express ocean container shipping into Tokyo/Yokohama port.
4 How does APEX ensure consistent edge sharpness without premature burr formation on thin foils?
Edge sharpness is governed by grinding wheel mesh selection, multi-axis CNC peripheral grinding parameters, and proprietary robotic edge honing. We utilize 800# to 2000# resin-bonded diamond wheels to ensure the cutting edge radius (r-value) is precisely controlled between 1 μm and 3 μm without edge feathering. Every batch is verified via 500x optical profile projection to guarantee burr-free foil separation.
5 Are your tungsten carbide raw materials certified conflict-free and compliant with Japanese environmental regulations?
Absolutely. Jiangxi Apex Carbide Co., Ltd. strictly adheres to the Responsible Minerals Initiative (RMI) standards, sourcing only from conflict-free certified smelters. Furthermore, our finished cemented carbide tools comply 100% with RoHS 2.0 (Directive 2011/65/EU and amendment 2015/863) and EU REACH regulations. Full third-party SGS/TÜV test reports are available upon request for corporate compliance audits.
6 What is your Minimum Order Quantity (MOQ) for custom prototype testing?
We support trial prototype evaluations with an MOQ of just 1 piece for standard sizes and 2 to 5 pieces for custom-engineered drawing-based blades. We understand that Japanese engineering audits require rigorous on-machine validation before approving a second-source supplier for mass manufacturing lines.
