This paper is for those who really want to understand why injection molding might be so expensive and how injection molding companies deduct their service pricing. The purpose of this piece is to take out the anxiety burden of sales engineers to tell the project cost when unprofessional RFQs are received, as well as an opposite side’s inconvenience to tell or not to tell the budget of the project.
The paper dives into details of overmolding (in both: conventional plastic injection molding and micro injection molding), reflects technologies used (insert molding, two-shot molding, low-pressure molding) and discusses benefits, applications, complexity, and innovations of overmolding.
Mold cavity is one of the most important elements in injection molding and has a huge impact on the structural design of the molded part which must be impeccable for manufacturing process to proceed as stated in the project. This article introduces to the injection molding process for different types of cavity molds, their advantages and disadvantages, as well as the cost of injection molding.
Insert molding is a single-shot injection molding process highly applicable in manufacturing across many (e.g., medical, electronics, aerospace) industries. Even though insert molding seems to be very similar to overmolding, these two injection molding technologies differ and have their own benefits and drawbacks.
One of the most common Injection Molding Dilemmas is how to make a right desicion whether to use Hot Runner Systems or Cold Runner Systems. This paper dives deep into the details of both systems and advises on how to make the best choice between hot and cold runners.
Design for manufacturing (DFM) refers to a process that optimizes the design of a component to make it less difficult to manufacture, cheaper, and more convenient to deal with. As design for manufacturing encounters the early stages, it is easier to optimize the product and reduce unnecessary steps and costs.
