Precision tool materials for medical manufacturing.
YOUR APPLICATION COMES FIRST
A clear specification starts a better technical conversation. Here is how to prepare your enquiry.
Tell us the workpiece material, machining process and tool or die design.
Share your preferred series, dimensions, crystal orientation and required geometry.
Include quantity, destination and target date so our team can discuss availability.
Start with SR or SN for precision finishing, SC for shaped tools and wear parts, STN/STT for dressing tools, and SD for wire-drawing die cores. Confirm suitability for your process with our team.
The SC series includes cuboids, cylinders and triangular prisms cut from in-house rough. Send a drawing to discuss non-standard geometries and dimensions.
Confirm dimensions, orientation, tolerances, quantity and availability. Our catalogue gives reference specifications; the final selection depends on your application.

TDHX / INSIDE THE OPERATION
From mineral selection to the final packed product, explore the facilities and equipment shown in the company brochure.



Original photographs from the TDHX company brochure.
Quarrying → raw-material sorting → crushing → grinding → packing → loading → logistics. Equipment includes vertical, ring-roller, Raymond and pneumatic grinding mills.
The brochures describe production sampling every 10 minutes, bag-weight checks every hour and quantity checks during loading. Request the test report and specification for your selected product.
25/50 kg woven bags, paper-plastic composite bags, kraft paper bags, bulk bags and PP bags. Custom packaging materials and printing are available according to the brochures.
Share your application, chemistry, particle size, whiteness, quantity, packaging and destination. The documented sales process moves from sample testing and quotation to trial samples and bulk shipment.
The supplied TDHX market brief identifies steel, refractories and metallurgy as the principal industrial applications. The Urals, Central Russia and Siberia are associated with fused, dead-burned and high-purity magnesia; Northwest Russia with refractory grades; and the Volga region with light-burned MgO, magnesium sulfate and some refractory products.
