Die And Molding Applications

Pascal supports more than the quick change of the molds and dies for die casting, injection molding and stamping. We also provide gas springs for the molds and dies themselves. A quality spring is one of the main components that ensure overall product quality.

Our nitrogen gas springs are ideal for a wide range of applications. They can improve the functionality of heavy-duty stamping dies and injection molds and can be used in many types of press machining applications. Advantages of the gas spring include higher initial contact force, higher closing and clamping forces, durability, and availability in compact sizes.

Pascal gas springs are available in many strokes and sizes to meet the required force within the die. Typical gas spring applications are lifting stock, drawing (to hold the bead), blanking (to strip the punch) and piercing (stripper plate, stripper unit and cam units). We stock many sizes of gas springs in our warehouse to provide same-day shipping.

The increased use of High Tensile Strength Steel (HTSS) in recent years has resulted in a growing need for automotive gas springs. HTSS is very strong yet lightweight, and the reduced weight improves the vehicle’s fuel efficiency without compromising safety. Also, because HTSS is brittle and difficult to form compared to conventional steel, more initial force is required than coil springs can achieve.

Nitrogen gas springs are ideal for HTSS projects because they have a much higher initial force and they can withstand consistent use longer than coil springs. While coil springs constant expansion and contraction can cause them to wear down quickly, gas springs are much more durable with a longer part service life.

Gas Springs for Stamping

In the stamping business, downtime resulting from frequent coil spring failure can be costly. Nitrogen gas springs for dies are a good alternative for reducing downtime and improving product quality. A die with coil springs can be retrofitted with Pascal gas springs with simple modifications to meet your needs.

Gas Springs for Press Machining

Gas springs have become popular in stamping die applications in recent years because gas springs have many advantages over conventional coil springs. Since they are compact and capable of producing high force, fewer springs for dies and molds are required to achieve the desired force, which means that the die can be built with less machining and less material, resulting in reduced weight and lower overall construction and maintenance time and cost.

Gas Springs for Injection Molding

In injection molding, gas springs can push ejector plates. Mold springs can exert much more force than coil springs, which means that fewer springs are necessary, and less machining for installation is required.
