We offer customized bolster plates and platens that improve machine rigidity, load distribution, dimensional accuracy, and long-term operational stability. We focus on fit accuracy, structural stability and delivery reliability, supporting both new machine production and aftermarket replacement.
A platen is a large structural plate used in machines such as injection molding machines and die casting equipment. It provides mounting support for molds and ensures accurate alignment during machine operation. Platens are designed to withstand high clamping forces, repeated stress cycles, and thermal expansion while maintaining excellent flatness and rigidity.
Bolster plates are thick support plates commonly used in stamping presses and hydraulic press machines. They are installed on the press bed or ram to support dies and tooling systems. Bolster plates distribute pressure evenly across the working surface and protect the machine structure from deformation caused by concentrated loads.
Both components are designed to provide structural stability, precision support, and long service life under heavy operating conditions.
Stamping and hydraulic press machines operate under extremely high pressure and repeated impact loads. In these applications, the quality and structural strength of the bolster plate significantly affect machine stability, tooling lifespan, and production accuracy.
NSPM manufactures heavy-duty bolster plates for mechanical presses, hydraulic presses, forging equipment, transfer presses, and metal forming systems. Our bolster plates are engineered to minimize deflection, improve rigidity, and maintain dimensional stability during continuous operation.
We provide fully customized machining services, including T-slots, precision drilling, threaded holes, guide pin holes, keyways, and surface grinding based on customer specifications.
Press bolster plates are mounted on the machine bed to support dies and absorb pressing forces generated during operation. These plates must provide excellent rigidity while maintaining accurate flatness under heavy loads.
Die support plates provide additional reinforcement for tooling systems during stamping and forming operations. Their main function is to support dies evenly and reduce localized stress concentration.
Adapter plates are used to connect different tooling systems or modify machine interfaces. They allow manufacturers to install various dies, molds, or production tools on the same machine platform.
Material selection is one of the most important factors affecting bolster plate performance, durability, and operational stability.
NSPM offers several proven material solutions for stamping and hydraulic press applications:

1.2311 / P20 steel is commonly selected for die support and functional plates due to its good machinability and dimensional stability.
For specialized forming applications involving high loads, high production cycles, or elevated temperatures, NSPM also provides customized alloy steel solutions designed according to customer operating conditions.
In addition to material selection, NSPM offers stress relieving, heat treatment, surface grinding, and anti-corrosion treatments to further improve component performance and service life.
Injection molding and die casting machines require highly rigid and dimensionally stable platens to support molds during high-pressure production processes. Platens directly affect mold alignment accuracy, clamping force distribution, and final product quality.
NSPM manufactures precision platens for various injection molding and die casting systems. Our products are widely used in automotive manufacturing, electronics production, industrial equipment, household appliances, and precision engineering industries.
By combining advanced machining technology with strict inspection procedures, NSPM ensures every platen achieves excellent flatness, rigidity, and dimensional accuracy.
The fixed platen is installed on the stationary side of the machine and supports one half of the mold system. During operation, it must resist clamping pressure and thermal stress while maintaining precise mold positioning.
The movable platen is connected to the machine clamping mechanism and repeatedly moves during mold opening and closing operations. It must maintain alignment accuracy while handling continuous mechanical stress.
Template plates serve as important support structures within molds and tooling systems. They help maintain mold alignment, distribute pressure evenly, and improve tooling stability during production.
Material performance is critical for platen reliability, especially in applications involving continuous clamping force, vibration, and thermal stress.
NSPM offers several material options for injection molding and die casting platens, including:
Ductile iron and gray iron are widely used for platen structures because of their excellent vibration damping capability and dimensional stability. These materials help reduce machine vibration and improve production consistency.
For template plates requiring precise machining and stable mechanical properties, 1.2311 / P20 steel is a common choice.
In high-temperature or heavy-duty operating conditions, NSPM can also provide customized alloy steel solutions with improved thermal resistance and structural strength.
