Hydraulic Rubber and Plastic Seal Successful Case
Our company's complete set of sealing production equipment is imported from the moldless processing production line produced by DMH in Austria. Hydraulic seals are suitable for use on various columns and jacks of coal mine comprehensive mining hydraulic support. It makes full use of the complementary properties of materials and has the advantages of small friction coefficient, long service life, and easy installation. Its specifications and dimensions can be fully matched with the existing column and jack groove dimensions, and it is a selected replacement product for coal mine comprehensive mining hydraulic support seals.
1. The raw materials are polymer materials specially used for coal mine hydraulic supports, which are resistant to hydrolysis, expansion, and small in compression, and can maintain a good sealing state for a long time.
2. Our company's series of seals have "standard" and "non-standard" boundaries, and can design and process seals of any size and any cross-section at any time according to user needs.
3. The sealing structure and size are always synchronized with the design and manufacturing of major coal mining machines. The unique process ensures the processing accuracy and sealing reliability of the product.
4. The piston seal has low dynamic friction under high pressure, good stability and long service life. Choosing our company's seal can maximize the effectiveness of the fully mechanized mining support, achieve stable support pressure and high reliability, and ensure safe production in coal mines. Reduce the number of shutdowns and extend the maintenance period of hydraulic supports, thereby improving the production efficiency of the entire fully mechanized mining face and reducing safety accidents. Save coal mining costs and enhance the competitiveness of enterprises in the market.
Precision Seal Design & Prototyping
◆ Custom Hydraulic Seals: Tailored solutions for coal mining equipment, including piston seals, rod seals, and wipers, with 0.01mm tolerance via Austrian DMH moldless production lines.
◆ Material Selection: Hydrolysis-resistant polymer compounds (tested to 30,000h lifespan under MA certification), with optional flame-retardant/anti-static additives for explosive atmospheres.
◆ Cross-Section Optimization: Finite Element Analysis (FEA)-supported design for dynamic sealing performance at pressures up to 500bar (7,250psi).
Rapid Emergency Replacement
◆ 24/7 Critical Response: Expedited production (72hr lead time) for mine downtime emergencies, including reverse engineering for obsolete seal profiles.
◆ On-Site Technical Support: Field installation guidance and pressure testing protocols compliant with GB/T 3452.3-2021 standards.
Non-Standard Component Solutions
◆ Retrofit Kits: Drop-in seal assemblies for legacy hydraulic supports (compatibility with JOY, Eickhoff, and domestic OEM groove dimensions).
◆ System Upgrades: Integrated sealing systems combining polyurethane/polyacetal components to replace traditional O-ring/gland configurations.

The cable clamp for coal mining machine is made of stamped steel plate as the skeleton and high-density polyethylene through injection molding.
There are a large number of flammable and explosive components such as gas dust in coal mines, and there are many metal equipment and instruments. When the equipment is moved and used, it is very likely to collide with the cable hook, which will produce sparks and lead to explosions.
The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.
The Y-ring is designed as a static seal for the cylinder, which can replace the traditional O-ring/retaining ring combination. Through its unique design and material, the allowable extrusion gap can reach 0.4mm at a pressure of 500bar.
Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.
The piston seal is a two-way seal, used in conjunction with two piston guide rings, and has a two-way sealing effect.
