If surface finish is important or the service temperature of finished part is expected to be high, higher mold temperature is recommended. Material Data Center d20-03 a comprehensive plastics database, calculation tools, CAE interfaces, a literature database and an application database.
It is recommended that the hold pressure time be maintained until the gate seal is completed. It is also important to review both short-term strength, mepital, elongation and impact strength etc and long-term properties creep, stress-relaxation and fatigue etc in determining which material to use.
Resistance to fuels and chemicals A thermoplastic material may show the changes in mechanical properties and dimensions in environments in contact with specific chemicals. PV limits In terms of frictional behavior, if pressure and speed gradually increase, at a certain point a material cannot withstand any f2-03 and start to molten.
The melting point ISO is useful information to set up processing temperatures and also determine the kepitaal at which it exists in a solid state. Check here, which other Kepital datasheets, application examples or technical articles are available in Material Data Center.

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. By setting optimum hold pressure, molded parts product with consistent dimensions can be produced. The test results of F to gasoline and diesel are shown in Figures and Heat deflection temperature The heat deflection temperature ISO 75 is the temperature at which specimen exhibits flexural deflection of 0.
Friction is the resistance to sliding of two paired surfaces and is divided by dynamical friction coefficient or static friction coefficient. KEPITAL FA is reinforced to have high rigidity with electrical conductivity as to meet requirement for high mechanical strength and low tendency to creep. Material Data Center is a leading international information system for the plastics industry. In order to obtain a high quality of product out of KEPITAL, the recommendations and check-points on the injection molding machine are the following:.
Over-heating or too long residence time in cylinder Insufficient gas vent Fast injection speed. Increase the cylinder temperature and mold temperature. Additional information about this material, like producer contact address, etc. Contamination with other material Black speck.
The later has both a crystalline region kepiyal an amorphous region in the final product. Thermal conductivity Unlike metals, most thermoplastic materials are insulators with a low thermal conductivity.
At temperatures exceeding the melting point, the specific heat in a molten state is exhibited. Resistance to light and weather With exposure to sunlight, plastics become very sensitive to ultraviolet rays. Because plastics have viscoelastic properties, creep strain is more readily exhibited than in metallic materials.
Behavior under long-term static stress When static stresses are loaded to thermoplastics constantly, not only does the initial strain occur but also an incremental kepitla is followed as kepitak goes by due to its viscoelastic property.
Rockwell Hardness of a plastic is divided into a M scale or a R scale, and the higher number the higher hardness. The shear strength is determined by dividing the force required to shear the specimen by the area of the sheared edge.

Finally part weight shows constant after the gate seal time. KEPITAL has the good stability in terms of mechanical properties and dimensions in contact with fuels even at evaluated temperature.
Impact strength can be measured in either notched or un-notched sample; however, it is generally evaluated after notch-processed on a specimen so that the stress of an impact load may be concentrated. In addition, if material stays in a cylinder under the condition of a blocked nozzle, formaldehyde gas can rapidly build up a high gaseous pressure in cylinder.
Radiation intensity and other conditions; filter combinations, temperature, cycle configuration, are specifically set up according to the test method. Tribological properties Tribological properties are highly affected by driving conditions such as pressure on the contacted surface, velocity, temperature, surface roughness etc. But on the other hand, if the stress is greater than the elastic limit, the material is deformed permanently after reduction of the stress.
The heat resistance of a plastic may be obtained from measurement of melting point, heat deflection temperature and linear expansion coefficient. Engineering parts are often subjected to the fatigue by stress or strain which is applied repeatedly and periodically over a long period.

In addition to natural colors, they are processed with various colors. The impact strength is the energy to withstand a dynamic impact rather than static stress. Too low holding pressure Wear of non-return valve Improper cushion.
Temperature and soaking time have an influence on those properties. Designing based on a dynamic structure analysis, obtained where a part is subjected to loading once, can only provide information if a part can be used without fracture under the single loading environment. It is therefore important to ensure the nozzle is never frozen or obstructed during processing.
