Buying Guide: Key Considerations For Choosing Mold Systems
Material and durability: Aluminum molds tend to be durable for repeated use, while plastic or CNC-machined polymer options offer lighter weight and easier release. Consider your production volume and storage space when selecting material.
Cavity count and lure size: More cavities boost batch output but increase mold footprint. Match the cavity count to your typical lure size and fishing style (e.g., 3-cavity 5″ baits for bass jigging, or 2-cavity for smaller 4″ designs).
Heat resistance and release method: Look for molds rated to withstand high temperatures to avoid warping and ensure smooth demolding. No oil or release agents listed is convenient but requires clean demolding and stable heat control.
Compatibility with injectors: Check the injection port size (commonly 5/8″) and overall compatibility with standard plastisol injectors. Ensure your equipment can seal tightly to prevent gaps and air bubbles.
Finish quality: CNC-machined molds offer smooth surfaces and zero gaps, which reduces flash and air pockets. A precise seal improves lures’ realism and reduces finishing work after demolding.
Customization potential: If color and scent customization is important, choose molds that support easy colorants and additives. Some molds are explicitly designed for oil-free demolding or easy release, which speeds up production.
