In the injection molding industry, Gas-Assisted Injection Molding (GAIM) is widely used for producing handles, grips, and structural parts thanks to its advantages: lightweighting, material saving, reduced sink marks, and improved dimensional stability.
However, in real production, many manufacturers face recurring issues:
Incomplete gas penetration
Flow marks / swirl marks on textured surfaces
Part warpage & deformation
These defects hurt appearance, assembly, and profit. In this post, we break down the practical, actionable solutions for these 3 major problems.
Polycarbonate (PC) is one of the most versatile engineering plastics, known for its exceptional impact resistance, optical clarity, and heat tolerance. Yet, for all its impressive properties, PC can be a formidable opponent on the injection molding floor. If you've ever struggled with flow marks, jetting, or short shots when molding PC, the culprit often isn't the machine—it's the gate and runner design.
A well-designed feeding system acts like a highway for molten plastic. A poorly designed one creates traffic jams. Here’s how to design gates for PC that give molders the widest possible processing window.
If you are in the business of exporting injection molds or plastic molds, you’ve likely encountered a common request from your overseas buyers: "Please provide the Certificate of Origin."
But here’s the challenge: Not all Certificates of Origin are the same. Issuing the wrong one could mean your customer pays unnecessary import duties—or worse, their goods get held up at customs.
This guide will walk you through everything you need to know about securing the right CO for your mold exports.
If you're manufacturing plastic products using glass fiber-reinforced polypropylene (PP+GF) , you already know one thing: this material is tough on molds.
Glass fibers act like tiny blades, scraping against the mold surface with every shot. Over time, this leads to wear, dimensional changes, and ultimately, mold failure.
But here's the good news: with the right tool steel selection and heat treatment strategy, you can extend mold life by 2-3 times – even with highly abrasive materials like PP+GF15 (15% glass-filled polypropylene).
The global plastic industry is facing a sudden and severe reality check. As military conflict escalates in the Middle East—most critically involving the closure of the Strait of Hormuz—the ripple effects are being felt far beyond the battlefield. For manufacturers, converters, and buyers of plastic raw materials, the past 48 hours have brought a wave of price hikes, supply fears, and market uncertainty.
As of March 3, 2026, the petrochemical supply chain is under its greatest pressure since the 2022 energy crisis. Here is what is happening, why it matters, and what to watch next.
Outdoor plastic products face relentless degradation from sunlight, temperature fluctuations, rain, humidity, and environmental pollutants. Over time, these factors cause plastic to yellow, chalk, crack, lose mechanical strength, and fade—undermining performance, aesthetics, and lifespan. Whether you’re manufacturing garden tools, outdoor furniture, automotive exterior parts, or industrial plastic components, optimizing weather resistance and UV stability is non-negotiable for delivering durable, long-lasting products.
In this guide, we’ll break down 5 actionable, industrial-grade strategies to enhance the outdoor durability of plastic materials (including PP, PE, ASA, PA, PC, and modified PP like SABIC PPcompound S3615). These methods cover material selection, additive formulation, processing, surface protection, and structural design—creating a full-cycle defense against outdoor aging.
