Avoid This Mistake When Ordering PC Materials For Trials

Choosing the right PC material is crucial for successful mold trials. A common oversight is treating similar grades as interchangeable. For instance, engineers often confuse Makrolon 2405 and Makrolon 2407, assuming they perform alike. This small error can lead to significant trial delays.

Key Differences: 2405 vs. 2407

While both are general-purpose polycarbonate grades, their properties differ. The primary distinction lies in their melt flow rate. This directly impacts how the material behaves during injection molding. Assuming they are the same is a frequent cause of failed trials.

Feature	Makrolon 2405	Makrolon 2407
Viscosity	Higher	Lower
Melt Flow Rate	Lower	Higher
Release Agent	Yes	Yes
Application	General Purpose	Thinner Walls, Complex Parts

Why It Matters

Using the wrong grade means your processing parameters will be off. This can result in molding defects, failed parts, and wasted time. The entire trial may need to be rescheduled while you wait for the correct material to arrive.

Mistakes in PC material selection often stem from overlooking subtle datasheet differences. The distinction between Makrolon 2405 and makrolon 2407 is a classic example. The higher melt flow of makrolon 2407 makes it ideal for parts with thin walls or complex geometries. It fills the mold more easily under less pressure.

Processing Implications

If a mold is designed for the flow properties of makrolon 2407, using the more viscous 2405 can cause issues. You might experience incomplete filling (short shots), higher internal stress, or surface defects. Adjusting machine parameters can only compensate so much. The material’s fundamental Rheology² dictates its behavior.

Temperature and Pressure Control

Controlling melt and mold temperature is essential. Too low, and you risk incomplete filling or high internal stress. Too high, and you can cause material degradation. Hold pressure is equally important; it compensates for material shrinkage as the part cools, preventing sinks and voids. Proper injection settings for 2407 are a balancing act.

Common Issue	Likely Cause	Solution
Splay Marks	Moisture in Resin	Dry material at 120°C for 4 hours
Sink Marks	Insufficient Hold Pressure	Increase hold pressure or time
Warping	Uneven Cooling	Adjust mold temperature; check cooling channels
Short Shots	Low Injection Speed/Pressure	Increase injection speed or melt temperature

Achieving optimal results with Makrolon 2407 depends on precise control over drying, temperature, and pressure. These PC molding parameters are not just guidelines; they are foundational to producing high-quality, defect-free parts consistently and efficiently during your mold trials.
