The difference between two production processes of silicone rubber heater?
There are currently two different production processes for silicone heaters:
Wire-wound type and etched foil type. Different production processes, the silicone produced heating pads also have different characteristics.
1. Winding type
Wire-wound Silicone Heater: Consists of thin, spaced-apart resistance wires wound around a fiberglass support.
Suitable for unusually shaped heating pads. They are durable, making them suitable for heaters that often need to be removed or reinstalled. They can be manufactured quickly and inexpensively without tools, making them ideal for low-volume projects and prototypes.
Etched type
Etched silicone heating pads use chemically etched foils.
They heat up faster, have higher power density and better heat transfer. They heat more evenly and last longer.
However, they are more prone to damage from repeated bending. Hence the need to pre-determine tooling costs, but have a more highly automated manufacturing process, which makes them more cost-effective for high-volume projects.
