Quality Improvement (PPAP)
Our injection molding cycle is generally automated. The majority of the process is carried out by machines and robotics that a sole operator can control and manage. Automation helps to reduce manufacturing expenses, as the labor overhead is significantly reduced. Not to mention being safer as well. We can pass these savings on to our clients. This type of automation also allows for making precise and accurate parts. Computer aided design (CAD) and computer aided manufacturing (CAM) further increase efficiency.
After the molds have been created to customer specifications and the presses have been preprogrammed, the actual injection molding process itself is rather expedient. Making use of thermoplastic, over-molding, insert and other types of injection molding, this process enables more parts in less time which equals reduced production expenses and a superior product. Not to mention it's also safer for employees.
In plastic injection molding, SIP, Inc. can easily use fillers in the injection molding process. These fillers lessen the density of the plastic while it is being molded and also help in adding greater strength to the piece after it has been molded. In verticals where parts need to be additionally resilient, plastic injection molding has additional options that other production methods just do not offer.
