CNC Machining vs. 3D Printing

While CNC machining (a subtractive process) and 3D printing (an additive process) are both manufacturing methods for plastic parts, there are pros and cons for each, and the right choice depends on your needs for your parts. Some of the advantages of CNC machining are: Materials: Since different plastic materials are available for CNC machining than for 3D printing, you can CNC machine prototypes out of the same base materials you’re going to use for your injection-molded production parts. This allows [...]

Design Guidelines for Plastic Part Moldability

Need a boss in your part so it can attach to another part? Did you know there are correct ways and incorrect ways to design a boss? Design a boss wrong and you could have thick sections that lead to sink marks. To help you avoid sink and other potential pitfalls in plastic part design, our Plastic Part Design Guidelines resource provides tips to help you avoid design mistakes that can lead to surface material and structural flaws in the [...]

Low Tool Setup Charge

When you use a contract manufacturer like ICOMold to run your production plastic parts, there are setup costs associated with every production run, and these costs are passed on to the customer in the form of a tool setup charge. The advantage of using ICOMold for your plastic injection molding project is that our tool setup charge is very low compared to our competitors. Our tool setup charge is a flat $150 for each production run, compared to the $500-$700 [...]

Calculating Plastic Injection Mold Shrinkage

This week we’d like to focus on one of the topics in the extensive online Knowledge Base on our website: Plastic injection mold shrinkage. So, what is “mold shrinkage?” It is the contraction of a plastic molded part as it cools after injection. The amount of shrinkage can vary depending on various factors like material type and wall thickness. It is the responsibility of the tooling engineer to calculate, and compensate for, mold shrinkage so that the final plastic part will [...]

How Online Quoting Compressed Time for Plastic Injection Molding

Driven by customization and personalization, the competitive factor of time-to-market has dictated quicker turnaround times for plastic products. The speed of everything in the manufacturing process leading up to fast parts – including rapid prototyping, and the quotation process – has been accelerated. Engineers today are under pressure to quickly design, collaborate and source parts. Fortunately, they have new digital tools at their fingertips that they didn’t have just a short year or two ago. Online quotation systems, in particular, have [...]

How Online Quoting Compressed Time for Plastic Injection Molding

As recently as a couple of years ago, it took engineers days or even weeks to obtain a quote for a custom plastic injection molding project. Today, the quotation processing time has been compressed to just a matter of hours. Through the Internet and some very complex, innovative online quotation systems, the automation of the quotation process has revolutionized the plastic injection molding industry. The Need For Speed Products today have an increasingly shorter lifespan. Think about how quickly new models [...]
