Thermal Product Solutions, a global manufacturer of thermal-processing equipment, announced the shipment of a Gruenberg Custom Conveyor Oven to the contact lens industry. This oven is designed and equipped for processes involving curing cast wafer assemblies.

The operating temperature of this conveyor oven is 75ºC to 100ºC while the maximum temperature is 120ºC. The oven consists of a cooled Infeed area, one heating zone, one cooling zone, an unload automatic stacking system, and two conveyor lanes side by side.

The construction of the conveyor oven including the main conveyor is stainless steel. The liner inside the oven is continuously welded to separate the oven environment from the insulation and prevents contamination of the product.
