Overcome Mold Parting Line Issues & Discover Cost Savings
PL-S® Parting Line Sealer ensures resin stays in the mold, preventing leaks and maintaining consistent wall thickness. It seals gaps along mold parting lines, cures during the cycle, and fuses to the part’s surface, leaving a smooth, professional finish. This saves materials, time, and reduces scrap rates.
Key Benefits:
Unsealed parting lines lead to resin loss, uneven wall thickness, and increased scrap. Each defective part represents wasted resources and rework time, impacting your bottom line. PL-S eliminates these hidden costs.
PL-S® Parting Line Sealer is a unique polymer compound that resists flow at high molding temperatures during the rotational molding cycle.
It is a pliable compound that cures in the mold during the molding process and fuses to the outer skin of the part. The excess material can be easily trimmed away using standard flash-removal tools.
PL-S Parting Line Sealer was developed for one reason…to keep your resin in the mold where it belongs during the molding cycle.
