Tribological properties Kepitaal properties are highly affected by driving conditions such as pressure on the contacted surface, velocity, temperature, t20-03 roughness etc. Dielectric strength measurement ASTM D of plastic is determined by dividing the voltage with a specimen thickness kspital incurs current when a test specimen prepared by injection molding is placed between two electrodes, and a voltage is incrementally increased from 0.
Thermal properties are important elements for establishing the processing conditions of a plastic material and service temperature of a finish part. In order to prevent odor nuisance, thermally damaged material can be cooled down in the water bath. Because the gate seal time changes mostly upon the shape of cross-section and mold temperature, f220-03 proper hold pressure time must be determined such that the weight and dimension of a molded product are within a certain range.
Lower the cylinder temperature Check for kepita vent Decrease injection speed. Please contact us at webmaster matweb. Increase clamping force Lower injection pressure or holding pressure Lower injection speed Repair mold.
In particular, when designing parts such as pressure resistant containers, screw fasteners, insert formations and insertion parts for a posttreatment process, the creep property of material must be considered in advance.
Finally part weight shows constant after the gate seal time.

In addition high back pressure may be used to eliminate unmelted particles. The melting point ISO is useful information to set f0-03 processing temperatures and also determine the temperature at which it exists in a solid state. Resistance to fuels and chemicals A thermoplastic material may show the changes in mechanical properties and dimensions in environments in contact with specific chemicals.

The heat deflection temperature ISO 75 is the temperature at which specimen exhibits flexural deflection of 0. Temperature dependency on mechanical properties KEPITAL maintains balanced physical and mechanical property characteristics over a wide range of temperatures.
Surface Resistivity Surface resistivity ASTM D is insulation resistance when certain voltage is applied across the surface of material.
A back pressure of bar is generally appropriate.
Low clamping force Too high injection pressure or holding pressure Too fast Injection speed Mold wear. Influence on flowability keptal found to depend greatly on molecular weight.
Material datasheets available free. In terms of frictional behavior, if pressure and speed gradually increase, at a certain point a material cannot withstand any further and start to molten. To obtain a good quality product, the mold temperature must be consistently maintained so that the temperature distribution in the mold may be achieved uniformly. In general, when the injection pressure increases, the shrinkage rate decreases.
KEPITAL FA is reinforced to have high rigidity with electrical conductivity as to meet requirement for high mechanical strength and low tendency to creep.

In general the friction force causes a surface temperature increases at high velocity and a squeak noise under a certain pressure.
The heat resistance of a plastic may be obtained from measurement of melting point, heat deflection temperature and linear expansion coefficient.
Increase holding pressure and time Increase mold temperature Gating at thick wall Check for non-return valve. Additional information about this material, like producer contact address, etc. Appropriate injection pressure generally ranges to bar. With exposure to sunlight, plastics become very sensitive to ultraviolet rays. It is also important to review both short-term strength, modulus, elongation and impact strength etc and long-term properties creep, stress-relaxation and fatigue etc in determining which material to use.

Improper compression zone length may not only over-heat material but also lack of pressure build-up in the plasticizing.
