Molding process of glass fiber and strengthened at roughly the same, but because of the flow is strengthen the difference before, so is the appropriate increase in injection pressure and injection speed, barrel temperature increase 10 to 40 ℃.Because of the glass fiber will be along the flow direction orientation in injection molding process, mechanical properties and shrinkage caused by strengthening, in the direction of orientation lead to products deformed, therefore, mold design, gate location, shape, reasonable, craft can increase the temperature of the mold, the product comes out in the hot water allow it to cool down slowly.In addition, the larger the proportion of the glass fiber, the greater the wear and tear on the plasticizing elements of the injection molding machine, preferably with a double metal screw and barrel.It is widely used in gears, bearings, fan blades, pump leaves, bicycle parts, auto parts, fishing gear and some precision engineering products.Has good abrasion resistance, heat resistance, oil resistance and chemical resistance, also greatly reduces the bibulous rate of the raw material and shrinkage rate, excellent dimensional stability and excellent mechanical strength.Compared with pure nylon reinforced nylon mechanical strength, rigidity, heat resistance, resistance to creep and fatigue strength greatly increased, elongation, molding shrinkage, moisture absorption, abrasion resistance decline. Performance mainly depends on the bonding strength of fiber and resin, content, ratio of length to diameter and orientation degree.Injection molding and extrusion molding.It is widely used in aerospace, automobile, machinery, chemical industry and other fields to make heat-resistant structural plastic parts.
A centrifugal pump CNC SLS SLA Vacumm casting tooling:
1. Principle of centrifugal pump.
Pump start before the pump first inflow tube filling with water, the water pump after the operation, the high-speed rotating impeller and the centrifugal force, under the action of the water in the impeller passage was thrown around, pressed into the volute, impeller entrance to form a vacuum, pools of water along the suction pipe in the outside world under the atmospheric pressure inhaled added to this space.The resulting water is then dumped by the impeller through the volute and into the pipe.Thus, if the impeller of centrifugal pump is continuously rotating, it can continuously absorb water and pressure water, and the water can continuously ascend from low to high or far away.To sum up, centrifugal pumps are referred to as centrifugal pumps because of centrifugal force generated by the high-speed rotation of impeller.
2. General characteristics of centrifugal pumps.
(1) water along the centrifugal pump flow direction is along the axial suction impeller, perpendicular to the axial flow, namely the in and out of each other becomes 90 ° in the direction of flow.
(2) due to rely on imported form vacuum suction impeller centrifugal pump, so before starting to pump and suction tube perfusion in water, or use the vacuum pump suction, to form a vacuum exhaust air, and the pump shell and the suction pipe must be strictly seal, shall not leak, otherwise not form a vacuum, also can't absorb water.
(3) absolutely can't be formed due to the impeller import vacuum, so centrifugal pump suction height is not more than 10 meters, coupled with the flow of the suction piping to bring down the loss, actually allow installation height (pump axis is apart from the height of the suction surface) is far less than 10 meters.If the installation is too high, do not absorb water;In addition, because the mountain area is lower than the atmospheric pressure in the plain, the installation height of the same water pump in the mountainous area, especially in the high mountain area, should be lowered, otherwise it will not be able to absorb water.
