Achieving precise adhesive application to improve quality & productivity

Bead quality is essential in both instances, in order to ensure structural integrity and anti-corrosion during BIW building and providing an effective seal against gas escaping from the battery pack during the cover joining process. Because the battery pack cannot be exposed to heat, adhesives and sealants, such as one component (1C) hot butyl, two component (2C) polyurethane or 2C silicone, that do not require oven curing, are the most appropriate materials for TIM and cover sealing. Regardless of the material, Atlas Copco dispensing technology enables the precise application of sealant with a uniform bead combined with the high flow rates required to maximise productivity. Atlas Copco’s UPHD heavy duty displacement pump range enables short filling times, with the ability to deliver a sealant volume of 165, 301 + 1200 cubic centimetres each double-stroke, making it the ideal choice for material volumes of up to 40,000 litres per year. The innovative UPHD displacement pumps is also designed from the outset to provide long-term durability against highly abrasive TIM.
