Micro injection molding

Micromolding - in-depth Insights

As most of modern devices are either getting smaller or requiring tinier components, the demand for plastic micro molding continues growing. Thus it is easy to guess - this article is going to dive us in peculiarities of micro injection molding technology.

Cost of injection molding

Cost of injection molding (includes calculator).xlsx

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.

Rapid injection molding, lead time

Rapid Injection Molding

In today fast-moving world companies have to deal with high market speeds. 'First to market wins' is still a prevailing notion. Rapid injection molding distinguishes itself from traditional injection molding mainly in respect of tooling and digitalization.

Overmolding

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.

Cavities

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.

Injection Molding Prototyping

In depth insights on the topic of prototyping for injection molding, reflecting the concept of injection molding prototyping itself, its relevance and process explained.

Insert 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.

Injection molding

Injection Molding Dilemmas: Hot or Cold Runners?

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.

Injection Mold Making: Types of Molds

A mold might be the most important (and expensive) tool used in plastic injection molding. This paper explores the two main types of molds: aluminum molds and steel molds and explains the process of mold making and the most relevant things to consider.

Design for Manufacturing for Plastic Injection Molding

Design for Manufacturing for Injection Molding

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.
