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.
Injection molding is the workhorse of modern manufacturing, turning plastic pellets into everything from tiny electronic components to large automotive parts. For engineers and product designers, understanding this process isn’t just about knowing the steps—it’s about mastering the details that separate a good part from a great one. Let’s break down the injection molding workflow, key parameters, and how to optimize for high-performance materials like PA6+30GF (BASF Ultramid B3EG6).
READ MOREIn injection molding, gas assist molding and insert molding are two fundamentally different specialized processes. But what if your product needs both—a hollow, lightweight structure and integrated metal components like threaded inserts or electrical contacts?
The good news: These technologies can be combined in a single mold, in one production cycle. This integrated approach creates products with both weight-saving hollow sections and durable metal-functional areas.
This comprehensive guide explains how gas assist and insert molding work together, the technical challenges, design principles, and when this combination makes sense for your application.
