Import Cartridge Heaters — Buy in Bulk from Supplier in India

The cartridge heaters offered by Magma Technologies are custom‑manufactured heating elements intended for concentrated heat delivery to solid metal components. The catalogue distinguishes two construction families: High Watt Density Swaged heaters, which use spirally wound NiCr wire on an MgO core that is compacted, and Low Watt Density heaters, where a helical NiCr coil is placed in an MgO‑filled tube without compaction. Both types are encased in a metallic sheath selected to match the required diameter and operating conditions. The supplier mentions that the heaters are machined to precise tolerances and straightness to ensure consistent performance.

NiCr resistance wire provides stable resistance over a wide temperature range, and the MgO insulation delivers high dielectric strength, a standard for cartridge heaters in industrial heating applications. Typical operating temperatures for such heaters fall between - 50 °C and 300 °C, with voltage ratings of 110 V or 220 V commonly supplied. Pressure resistance is usually rated up to 8 bar, and dimensional tolerances are generally ±0.5 mm on the outer tube. These parameters align with the requirements of equipment such as injection molding machines, heat‑treatment furnaces and fluid‑heating circuits.

Customers include manufacturers of metal dies, plastic extrusion tools and process equipment that need localized, high‑density heat. Magma Technologies indicates flexible order quantities and can ship under FOB or CIF conditions from its Mumbai facility. Prospective buyers should confirm the specific watt density, voltage, and end‑cap material needed for their application, as well as lead‑time, payment method and any certification requirements before finalising the purchase.

Magma Technologies is situated at 111/112, Ravi Raj Industrial Estate, B/h. Gaurav Dharamkanta Mira Bhayander Road, Bhayander East, Mumbai, Maharashtra, India (postal code 401105). The company is listed as an imported‑tier supplier with a harbor trust rating, indicating participation in international trade and compliance with basic verification checks.

The firm manufactures a variety of cartridge heaters, offering both high‑watt‑density swaged designs and low‑watt‑density models for diverse industrial uses. Platform data shows a 0 % response rate and no recorded average response time, so buyers should anticipate a longer communication cycle and may wish to request a dedicated sales contact.
