Payment Terms:

Payment terms are basically negotiable under following rules:

For products we have in stock, usually we ask for full payment upon ordering.

For products of customized specifications, or painted / printed as required, or of special materials, normally we ask for full payment upon ordering.

For regular size wear parts/ consumables/ spares, usually we request 30% payment before sending order to our plant, and the balance before shipment.

Key Parameters

For most applications, the thermal performance and temperature distribution are the two key design parameters. In order to avoid any hotspots and to maintain a uniform temperature distribution across a substrate, the circuit design can be optimized by changing the localized power density of the resistor circuit. An optimized heater design helps to control the heater output and modulate the local temperatures across the heater substrate. In cases where there is a requirement of 2 or more heating zones with different output power over a relatively small area, a thick film heater can be designed to achieve a zonal heating pattern on a single substrate.

Tubular (Sheathed) Heating Elements

Tubular (sheathed) elements normally comprise a fine coil of nichrome (NiCr) resistance heating alloy wire, that is located in a metallic tube (of copper or stainless steel alloys such as Incoloy) and insulated by magnesium oxide powder. To keep moisture out of the hygroscopic insulator, the ends are equipped with beads of insulating material such as ceramic or silicone rubber, or a combination of both. The tube is drawn through a die to compress the powder and maximize heat transmission. These can be a straight rod (as in toaster ovens) or bent to a shape to span an area to be heated (such as in electric stoves, ovens, and coffee makers).
