In injection molds, die-casting molds, and various automated mold systems, Hydraulic Cylinders are essential power components that provide reliable linear motion for critical mold actions such as slider core-pulling, ejection plate movement, mold opening and closing, and unscrewing mechanisms. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for sealing performance, durability, and precision of hydraulic cylinders. Every cylinder undergoes precision machining and rigorous testing to ensure no leakage, stable performance, and long service life during long-term high-frequency operation.
Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the material selection, sealing structure, piston rod durability, and overall reliability of hydraulic cylinders. Only those with robust construction, reliable sealing, and exceptional durability are approved for our supply system.
Premium Materials, Robust Construction
Our hydraulic cylinders are manufactured from high-strength steel materials with specialized heat treatment and welding processes, ensuring exceptional fatigue resistance even under high pressure and heavy loads. Cylinder barrels feature precision honed inner surfaces for optimal piston sealing and smooth operation. Piston rods undergo hard chrome plating with special surface treatment to provide outstanding wear resistance and corrosion resistance, significantly extending service life.
Precision Machining, Reliable Performance
Cylinder components are precision machined using advanced CNC equipment, with tight tolerances ensuring consistent performance across all operating conditions. The low-friction sealing system, crafted from specially designed materials, meets the demands for low starting pressure, minimal oil film, and rapid response, optimizing operational efficiency.
Multiple Structure Types, Wide Application Range
We offer various structural types of hydraulic cylinders to meet different mold requirements:
Standard Tie-Rod Cylinders: Designed according to ISO 6020/2 standards, with working pressure up to 210 bar and bore sizes from 25mm to 200mm. Available with multiple mounting styles and piston rod options.
Compact Cylinders: Space-saving design with integrated electrical box for precise position control, ideal for limited clearance applications in injection molds and die-casting equipment.
Self-Locking Cylinders: Feature mechanical automatic locking at stroke end, eliminating the need for auxiliary locking mechanisms and simplifying mold structure. Particularly suitable for applications requiring secure position holding.
High-Temperature Cylinders: Specially designed for die-casting applications, available with integrated cooling systems to withstand extreme operating conditions.
Two-Stage Knockout Cylinders: Double-acting two-stage design for core extraction in die-casting molds, contributing to space-saving in the mold system.

Excellent Sealing, Leak-Proof Performance
Multi-layer sealing protection with high-quality seals made from fluororubber or nitrile rubber withstands high temperatures, oil resistance, and corrosion, ensuring long-term leak-free operation under high-pressure conditions. Effective oil drain design addresses issues such as heavy oil film buildup and prevents trapped pressure in the sealing system.
Position Sensing Options
For applications requiring precise position control, we offer cylinders with:
Magnetic switches for stroke feedback to injection molding machines
Inductive sensors for position detection
Mechanical sensor options for reliable end-of-stroke indication
Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common bore sizes, strokes, and mounting types for quick dispatch. For non-standard customization, based on your mold structure and application requirements, we offer custom hydraulic cylinders with special bore sizes, special strokes, special rod end connections, magnetic switch configurations, high-temperature versions, and integrated cooling systems.
