In order to remain profitable, businesses have to cut production costs, but ensuring quality is not compromised as well. Two shot injection molding stands out as among the most innovative methods used nowadays to minimize these expenses. resultant from this technique is that it allows for the production of parts that are made up of different materials in a single step. Despite this advantage however, some professionals tend to combine precision, efficiency and flexibility as a way of enhancing their work through two shot injection molding.
Understanding the Process of Two Shot Injection Molding
Alternatively known as double injection molding process involves using two differing substances or resins during one manufacturing cycle only. First off there is an initial injection into a particular mold before being followed by another injection on different resin which fuses with latter at end stage such that they become solidifiable together through process. The other advantage of multi material parts made through this technology is that they are easier to use than others that involve several processes through which these materials have to pass before they were used.
Getting Rid of Unnecessary Production Steps in Manufacturing
It is in this regard that two shot injection molding becomes more favourable compared to other processes as seen in the next section. Basically, the creation of multi-material parts would require the use of several molds as well as different injection molding cycles for each material. This not only takes time but also increases production costs due to additional steps taken during manufacturing. Nevertheless, multi material parts can be manufactured through two shot injection molding process without having multiple molds; machines and labor that translates into time saving together with decreased expenses on behalf of manufacturers. Both time and production costs are however reduced by simplifying the manufacturing process.
Reducing Scrap Rate
Another method of whittling down on production expenses using 2 Shot Injection Molding is by reducing scrap rate. Much scrap is derived when there is more than one material being molded traditionally. This excess material must be properly handled leading to extra charges for either disposal or recycling in other cases. As opposed to others which may lead to much wastage such as traditional molding techniques where there are various material’s in use, two (or dual) shot method is very efficient with regard to the use of materials as it injects only the amount of material required by the model.
Enhancing Product Design and Reducing Assembly Costs
2 Shot Injection Molding also enables people to develop features within components hence making an end product have a complex design. One-way manufacturers achieve this is by incorporating built-in functions using both materials on a single mold, i.e., soft-touch surfaces through overmolding or electrical insulation on multi-coloured parts.
Reduction in Tooling and Equipment Costs
Traditionally tooling and equipment costs form a significant portion of the total expenses incurred in injection molding due to the need for several molds and machines for multi-material parts. By so doing, two shot injection molding reduces tooling requirements because different materials can be used together inside a common die, which implies less machines and molds are necessary for manufacturing.
Conclusion
Two shot injection molding is a powerful tool in lowering production costs while making products better than before. As a result, companies can now fabricate multi-material components in an economical and timely manner by simplifying their processes, reducing wastage (material), as well as eliminating the secondary assembly stage.
