Chinaplas, SIPA, Hall 4.1 Booth C71 The advantage of mould conversion over buying a brand new mould lies in the lower capital investment involved. SIPA’s mould refurbishing and conversion services in China are an important element of its PET preform and bottle mould offering.The existing mould shoe is reused, and return of investment is faster. Customers can choose which is best for them by having a mould audit carried out by SIPA experts. The state of wear of mould components can be assessed in their own plant, and different options on refurbishing or conversion can be proposed.
The mould refurbishing and conversion services complement SIPA’s in-house capability to develop and produce high performance moulds and hot runners in-house. The hot half of each SIPA mould requires maintenance only after five million cycles, and it is possible to maintain components such as piston, flange O-rings and pin valves without opening the whole mould.
The company’s range of solutions benefits from SIPA’s special focus on reducing energy consumption. With better distribution flow and a higher water temperature (14-15°C instead of 8°C), water consumption is minimised and performance in terms of condensation reduction is improved.
The smooth, polished, rounded profiles on SIPA hot runners reduce stress on material, resulting in better preform quality and a reduced acetaldehyde (AA) level. Mould systems also exhibit enhanced cooling performance, resulting in high quality preforms, maximum productivity and reduced production costs.
SIPA’s service center in Hangzhou, China, in operation since 2004, complements two others in Italy and the USA.
