PREFORM PRODUCTION PETplanet Insider Vol. 23 No. 04/22 www.petpla.net 15 personalised water diagram and each stack has a dedicated design. The reason, according to Sipa, is to make use of the best software systems currently on the market and customise them to provide high-speed mould analysis. This activity is incorporated into the engineering development flow, without having an impact on the lead time of the product. The impact that it does have is in the creation of a product with high performance, both in terms of cycle time and consumption in utilities that are all 100% tested internally before delivering the tool to the customer. Mapping characteristics Validation of the various analytical evaluations is carried out during the first stages of testing. Before conducting any functional testing, the moulds that are designed and built on the basis of these calculations are subject to measurements of the characteristic curves of flow rate and power on a special test bench. This activity is important, because it allows for validation of the project assumptions, and to increase the capacity of Sipa’s database through the acquisition of new experiences, further refining the calculation methods behind the company’s mould design capabilities. Sipa offers various adaptation kits that allow the installation of the same mould on different models of injection moulding machine to make customer operations as flexible and economical as possible. The benefits of the state-of-the-art Sipa toolings are accessible globally to all preform producers, since Sipa preform moulds can be interfaced with the vast majority of injection moulding machines that are used in this application. www.sipasolutions.com The number of cavities is one of the variables that has to be considered when optimising the preform production process. Cooling systems have to be designed in relation to the mould and machine size but also in relation to the geometry of the preform.
