Injection Molding Tolerances: 3 Things Engineers Must Know

Undoubtedly, design engineers assume a lot of responsibility when developing parts with tight injection molding tolerances. When margins are as slim as +/- .001 inches in some medical, automotive, industrial, and consumer applications it’s a given that design drives injection-molded part performance. Likewise, the design is the first place to seek answers should something go wrong with the tight tolerance part.

Managing tight tolerance injection molding — and, by extension, taking some pressure off of designers — is done most effectively when you follow these three expert tips:

Resin Shortage Update: What 2021 May Be Teaching Us About 2022

Viewing 2021 through the lens of the resin shortage, the year went out much like it came in.

Q4 found commodity resins polypropylene (PP) and polyethylene (PE) available in greater quantities at lower prices.1 However, for many manufacturers, custom injection molding partners, and other supply chain vendors, the late-year good news was overshadowed by resin shortage challenges that will likely continue to pervade the plastics industry in 2022.

3 Must-Have Characteristics in a Custom Injection Molding Partnership

The widespread and ongoing disruptions in the plastics industry has given rise to a certain degree of panic. Manufacturers and suppliers are at the mercy of broken supply chains, and solutions for resins, service, and delivery aren’t always readily available.

How Molder Materials Expertise Benefits Automotive Plastic Components

Automotive plastic components aren’t limited to sleek dashboards, seats, floor mats, and other automotive plastic design details that attract buyers. These features may provide a degree of protection, but a vehicle’s overall safety and performance are largely dictated by often unseen under-the-hood plastic car parts.

4 Benefits of Managing Molding Risk Probability with DfM and FMEA

Generally speaking, Design for Manufacturability (DfM) is the process of consciously and proactively designing products to optimize all facets of manufacturing. 

DfM methodology aligns engineering and production in the design phase, ensuring cost and time efficiencies, superior quality, regulatory compliance, and end-user satisfaction.

Central to maximizing these DfM benefits is prioritizing Failure Mode Effect Analysis (FMEA) within the larger plastic part analysis to assess risk probability. Identifying and addressing problems early in the product development process prevents costly issues that could impact manufacturability such as plastics selection, tight tolerances, and secondary operations.

Resin Shortage 2021: Update on What’s Now, New, and Next

As Hurricane Ida unleashed its Category 4 fury on the state of Louisiana, plastics industry professionals kept a wary eye on the storm’s path. The repercussions of Hurricane Laura and Winter Storm Uri upended the resins market, which is still struggling. As the fifth strongest hurricane to ever make landfall in the continental United States1, Ida could have easily wiped out any progress made toward market restoration.

But, for the most part, Ida spared the plastics industry from further devastation. The hurricane veered away from the hub of resin production facilities in western Louisiana and eastern Texas, some of which were just coming back online.
