XB-100 Grooving | Crimping | and Sealing Machine for RTD and PT100

XB-100 Grooving | Crimping | and Sealing Machine for RTD and PT100
The XB-100 is a high-precision electro-pneumatic crimping and grooving machine designed to handle tubes, capillaries, and metal sheaths with outer diameters ranging from 2 mm to 10 mm. Its operational principle is based on the controlled and symmetrical application of circumferential pressure (grooving effect) using high-alloy interchangeable molds. This controlled plastic deformation securely fastens internal platinum resistance elements (in the case of PT100 sensors) or insulating gaskets, creating a flawless internal mechanical lock that prevents axial displacement and provides a solid foundation for subsequent airtight sealing.

What is MI Cable Processing Machinery and How Does It Work?

MI (Mineral Insulated) cable processing machinery consists of highly specialized industrial units engineered to cut, strip, calibrate, and seal metal-sheathed cables insulated with highly compacted magnesium oxide (MgO) powder.

Processing mineral insulated cables is a critical step in manufacturing heavy-duty industrial heaters and thermal sensors. Because magnesium oxide is highly hygroscopic, any exposure to ambient air causes it to absorb moisture instantly, destroying its dielectric insulation properties. Heatecx machinery is specifically engineered to perform ultra-fast, clean, and highly repeatable operations, ensuring that internal conductors and the core insulation remain entirely dry and structurally sound before the final sealing phase.

Product Types Within This Subcategory

  • Precision Cutting Machines (CT Series): Equipped with high-durability cutting wheels and pneumatic clamping systems, the CT Series delivers clean perimetrical cuts on tough metallic outer sheaths without crushing or causing ovality.
  • Pneumatic & Hydraulic MI Cable Strippers: Power-adjustable workstations designed to strip away the outer metal jacket cleanly, exposing internal thermocouple wires (Type K, J, N) or copper cores without nicking or scratching the conductors.
  • Hermetic Sealing & End-Welding Stations: Automated or semi-automated units built to apply epoxies, resins, or execute micro-TIG/laser welding to instantly protect the exposed magnesium oxide insulation from moisture ingress.
