Preloading and Locking Core Pull Cylinders provide exceptional performance in Die Casting applications where zero core movement is desired to reduce flash and post flash operations. Use of KOR-LOK® often allows injecting faster and harder to eliminate porosity and produce consistent part weights shot after shot. Proper sizing can eliminate flashing of the part borders in most applications, making net shape die casting possible. General usage of the product follows the general sizing methods for all applications, however, PFA provides some additional guidance for some die casting situations involving long cores and high speed injection.
