We produce the PU Springs with Polyester type prepolymer and MOCA. It is widely used as Puncher Spring. Compared with metal or normal rubber springs, PU puncher spring is much better in performance, quality stability and working life. The finish products are also with better size accuracy. It improves the production efficiency.   
PU springs are widely used on Auto production lines as mould spring, puncher spring.
Highlight 
1 It is the most versatile, toughest, abrasion resistance elastomer available. It is as soft as Shore A durometer 10 and hard as Shore D scale durometer 85.
2 It could be cast into practically any shape, size or complex geometry desired wheels, gears, O rings, gaskets, tires, roller blades, skate boards etc. 
3 It can be formulated with high resistance to stresses and it tends to maintain shape and mechanical properties aster fatigue stressing.
4 Casting Polyurethane maybe pigmented to resist degradation by elevated atmospheric oxygen and ozone atmospheric concentrations.
5 Many cast polyurethane elastomers compounds remain flexible at extreme low temperatures and possess outstanding resistance to thermal shock.  Low temperature resistance of polyurethanes make cast parts very practical in extreme arctic conditions.
6 Casting polyurethane parts can be made flame resistance by incorporating flame retardants into their formulas. 
7 Polyurethane can be cast with coefficients of friction varying from very low, for items like bushings, bearings or wear strips, or very high, for items like tries or rollers.

Cypher SPRSEALS - it starts with seals


Since 1998, in the field of mechanical seal work and control, we have made step-by-step efforts to overcome the limitations and difficulties of the factors that affect the stability of the sealing performance, such as the material and the shape of the sealing lip.
Since 2000, continuous improvement and optimization of polyurethane elastomer materials and research on mixing with different materials and chemical raw materials. While the physical properties are balanced, new material performances after different chemical mixtures are also deeply developed.

Regarding the mixing research and development of nitrile rubber, hydrogenated nitrile rubber, silicone rubber, fluorinated rubber and various metal powders, countless deployment tests have also successfully realized the ideal special sealing material.
In the development and improvement of polyamide (nylon resin), polytetrafluoroethylene, and phenolic resin, we also ushered in a rapid increase in the number of our European customers and a doubled increase in sales in the Asian market.

We are researching dust seals (DKBI), piston rod seals (IDI, IUH, HBY), support rings (KZT,), piston seals (OUH, SPGO) in conventional hydraulic sealing systems day after day ), anti-wear rings/anti-wear rings (WR, SPGW) and are suitable for all kinds of jib cylinders, cantilever cylinders, bucket cylinders, lifting cylinders, and power steering cylinders.
Including the research and development and iterative production of the sealing ring of the hydraulic breaker, there have also been more new breakthroughs.

Thank you very much for your attention. If you have any demand for sealing system solutions, please be sure to contact me. I will cooperate with you in an honest and professional manner.
