Inflatable Fender Take You Through The Fender Mold

Yutung Industrial Limited | Updated: Oct 16, 2017

The structural design essentials and working process of two-plate latent gate injection mold, through the use of typical core structure, multi-spring top-out reset system, make the die life and reliability greatly improved. Through the continuous optimization of processing technology, control of machining precision and improvement of the die-casting technology in practice, the timing and the manufacturing cycle of die are greatly shortened, the labor productivity is improved and the manufacturing cost of die is reduced.Inflatable Fender

The product after forming requirements of smooth surface, no impact on the appearance of the reducing, weld marks, silver, color separations, lack of material, flying edge, cracks and deformation and other process defects. Fender Contour with tyre ensures good uniform clearance during circumferential direction. The plastic parts are properly thickened to ensure that their assembly is solid and reliable, but there is no interference. The dimension precision of the parts is carried out according to the GB/T14486-MT5 level, and the inner surface roughness of the plastic parts is Ra1.6μm, the outer surface roughness of the plastic parts is Ra0.8μm. In order to facilitate the removal of plastic parts from the injection mold and to ensure that the surface of the plastic parts are not pulled, the demoulding gradient is set to 1.5 °. At the junction of plastic parts, the proper fillet transition is used to avoid the stress concentration and crack of plastic parts. In order not to affect the appearance of the product, decided to use latent gate feed.Inflatable Fender

Considering the machining process and the latent gate of the moving and fixed mould core, the reasonable placement of the gating system, the parting surface, will not affect the dimensional precision and appearance of the plastic parts, avoid the flying edge, but also make the plastic intact, in favor of demoulding, and make the plastic parts remain in the movable mode, which is convenient for the plastic parts. The position of the exhaust groove is selected at the end of the shunt channel and the fusion line of the molten plastic body, exhaust groove depth ≤0.05mm, the width of 10mm, in case of overflow, while the plastic parts can also be through the split surface and dynamic die core and the top bar, the fixed mold core of the gap between the exhaust to ensure that the entire plastic parts good exhaust.Inflatable Fender
