Today's KNOWLEDGE Share : Choosing an Extruder Isn’t About Size but It’s About Suitability

Image
Today's KNOWLEDGE Share ⚙️ Extrusion Series Part 1: Choosing an Extruder Isn’t About Size but It’s About Suitability ▪️ Bigger isn’t always better. Smaller isn’t always worse. Think of an extruder screw like a car engine. A massive V8 looks great on paper, but if you’re stuck in city traffic, all that power turns into heat, waste, and noise. Same thing on a cable line: run thin insulation on a big screw, and the melt lingers too long in the barrel. Residence time stretches, temperature control drifts, and you start cooking polymer instead of shaping it. Flip it. A small screw is a 1.3-liter turbo which is fast, efficient, perfect for low-wall runs. But overload it with thick walls or high throughput and it gasps; pressure spikes, melt swings, higher shear rate and mixing turns uneven. ▪️ What Actually Matters 1. Barrel diameter → defines throughput capacity. 2. L/D ratio → controls how completely the polymer melts and mixes. 3. Compression ratio → stabilizes melt pressure; critical...

Today's KNOWLEDGE Share : Quality Checkpoints in Plastic Production

Image
Today's KNOWLEDGE Share Quality Checkpoints in Plastic Production In plastic manufacturing, quality isn’t just about the final inspection—it’s a continuous process built into every stage of production. Here are a few key checkpoints engineers rely on: ✅ Shrinkage Control – Materials shrink as they cool. Understanding the behavior of each plastic type helps engineers predict and adjust for this. ✅ Surface Defect Detection – Flow lines, weld marks, or sink spots can indicate issues in mold design, temperature, or injection speed. ✅ Tolerance Measurement – Precision tools (like calipers or CMMs) ensure critical dimensions stay within spec—especially for parts that need to fit or move. ✅ Material Verification – Consistency in resin type, additives, and batch quality is essential for repeatability. A good process is not just about catching defects—it’s about preventing them from the start, often beginning with proper DFM and mold design. Understan...

Arkema participates in the creation of a recyclable speed board to set new records

Image
  At JEC World 2026, Arkema and Zephir Project introduced a prototype of an eco-designed speed board made with Elium® resin, the first recyclable liquid thermoplastic resin. This board incorporates materials that promote circularity right from the design stage, paving the way for a new generation of composite parts that combine performance, precision, and recyclability. By joining the Zephir Project, #Arkema is once again using extreme #sports environments as testing grounds to unlock the potential of its materials. Exposed to particularly high stress levels in terms of acceleration, stability, and rigidity during the pursuit of sailing speed records,  #Elium®  resin enables the design of high-performance structural components while remaining fully chemically #recyclable : through a depolymerization process, the fibers and resin can be separated and then recycled, with the resin subsequently reused to produce recycled resin, thereby reinforcing the c...
