Performance cooling units target composite processing

A new range of cooling units from RocTool (Le Bourget du Lac, France) is designed to maximize the efficiency of the company's tool surface induction heating processes for injection molding and deliver parts with superior surface properties in minimal cycle times. With the C2V, part of the new C-series, cooling time can be cut by reducing the flow of coolant to a laminar state during heating, while accelerating the flow to a turbulent state during cooling.

 

New cooling unit reduces cycle time for tool surface induction heating processes.

"It is a great cycle time improvement and an extra cooling control capability. It's a real technological breakthrough that enables our users to have better control over the temperature changes and save valuable production time!" enthuses Jean-Francois Martinez, RocTool's Manager for Systems and Peripherals. "RocTool Systems & Engineering teams have developed a wide range of new performance cooling units to meet the manufacturers' growing demand in our Heat & Cool technologies in production globally" he adds.

Especially designed for composite processing, the RocTool C-series has been developed to improve the complete cycle time by purging the water from the mold in order to reduce the heating time and managing the water flow during the cooling time. "Our C2V unit is used with a water pressure network higher than 3 bar at 100 l/min., whereas our C6, C12 and C24 units are used with a water pressure network at 3 bar maximum, the flowrate depending on the model chosen. During the purging sequence, water mixed with compressed air is sent back to a tank to prevent any turbulence in the water network" adds Martinez.

RocTool also offers the T9; a compact thermoregulation unit offering a greater cooling power at 140kW when standard equipment does not exceed 40kW, as well as high pressure and controlled flow rates.
