To complete our range of solutions, we design and produce in-house blowing molds to fit our systems as well as most of the major brands of stretch blow molder machines and we offer a complete service of container design and prototyping. Contiform Speed for production of containers with up to 2.0 L. Models: Contiformfor production of containers with up to 3.5 L. In the latter process a preform, often similar to a test tube with a threaded end, is. The modular design of the Contiformallows for individual arrangements of equipment. Our solutions for the production of PET containers include high-speed rotary blowmolding systems, the XTRA range, linear blowmolding systems, the highly flexible SFL range of machines as well as high-speed 1-step systems, the ECS FX and medium low-speed 1-step systems, the ECS SP range. The two principal types of blow molding process are extrusion blow molding and injection blow molding. Many thermoplastics, including polystyrene, PC and. Two moulds are needed for injection blow moulding: a preform mould and a blow mould for. The preform is then reheated and blow molded. Only the body of the preform is blown up. In contrast with the one-stage SBM, these preforms are stored and fed later (after cooling) into the blow-molding machine. This process involves the manufacture of struc-turally amorphous semi-products, called preforms, made by injection molding of PET resin. SIPA has always maintained the objective of serving its customers in the broadest and most responsive way and, by offering the full range of solutions for container production, we are able to support customers with expert advice on the most suitable system to satisfy their specific needs. RHB uses pre-forms that are injection molded and inventoried. stretch-blow molding (SBM) process is probably the most popular. SIPA has held a unique position in the market as the sole manufacturer supplying both 1-step and 2-step solutions as well as injection and blowing molds for SIPA and non SIPA machines. Blow molding process mould-blow molding mold is referred to as blow mould. The 2-step process features the manufacture of plastic containers in two separate stages: first preforms are injection molded on an injection machine and then are re-heated and stretch-blown on a blowing machine. The preform moulding die (extrusion die, injection die) has been mentioned above. The 1-step process, based on the concept of integrating the preform injection process with the preform stretch-blowing process, results in a container obtained directly from plastic resin in a single machine. The manufacture of PET containers can be made with a 1-step or a 2-step process.
