Blow Mold Parts
Thai Auto Pressparts Co. Ltd. ('TAP'), located in Rayong Province, is a subsidiary of Thai Rung Union Car Plc and the group's main production base for pressed metal parts and for plastic parts for the OEM automotive market.

Manufacturing Process
TAP uses the extrusion blow molding ('EBM') process to produce plastic parts such as spoilers. The plastic is supplied in pallets and has to be melted and extruded into a hollow tube called a parison, which is then placed in a cooled metal mold consisting of two shell-like halves. The shells close onto the parison, and air is blown into it, inflating it against the inside of the mold into the shape of the part. After the plastic has cooled sufficiently, the mold is opened and the part taken out. The part can either be left to cool down of its own accord, or transferred into a post-cooling device to achieve shorter cycle times.

Quality checks of every product are carried out at each step of the manufacturing process. Innovative processes enable us to make substantial gains in productivity and competitiveness while adhering to the most stringent quality standards for the benefit of our customers. 

           With customers increasingly focusing on post-delivery product performance, TAP has developed feedback and continuous improvement systems to interact with our customers' organizations. This information is fed back into the product development process and shared as appropriate with suppliers and customers.
