Plastic Injection Mold Removing
The customer of Jacky Technology (Dongguan) CO.,LTD is always to check with us whether the mold can injection good product out if the mold is moved. plastic is one of the practical processes for the mass production. In the injection process, the mold has the most problems, and it is the most important factor in the plastic production line. It will directly affect production efficiency , cost and delivery time. Mold problems are mainly concentrated in mold component damage, product quality defects and mold sharpening, which is plagued industry. Only these key points are handled correctly. Injection will be smoothly which is also the mode-adjusting technology.
Jacky Technology (Dongguan) CO.,LTD will be changed the environment for the mold so that products are out of tolerance after moving, size is a serious flaw in plastic parts. We should be first check the design of the mold to eliminate the reasons for design and manufacture. If the tolerance is related to the thickness of the material, we should double check material hardness and thickness.
In the plastic production process, the size is out of tolerance, mainly due to the wear of the mold, poor positioning and deformation of the workpiece. The edge of the mold is worn. It will cause the burr to be too large or the size isalso larger, the punching becomes smaller, and the flatness is too poor, so the mold should be sharpened or replaced. Poor positioning and guidance includes no guide, guide pin or other positioning device does not work, the feeder does not relax, the positioning block wears too long, the feed distance is too long, the length of the guide plate is wrong or the guide gap is too large. The parts are deformed during production, mainly including impact deformation. For example, the blowing pressure of the product is too strong or the gravity falls. The impact is too large. When the material is squeezed or deformed during discharge, the discharge position should be cleared or the discharge space should be increased. : Ejection is improperly deformed. For example, when the top pin is improperly formulated, the spring force is not suitable, or the ejection force is too long, the elastic force should be adjusted or the position or the number of pins should be changed; Some curved parts cannot allow the material to overlap, and must be dropped every time. When the dish strain occurs, the pressure pad can be used to eliminate it; the punching and shearing deformation is mainly due to the material distortion. The size is increased or the center is asymmetrical; the deformation of the chip is caused by the floating of the scrap or the fines remaining on the die face or the foreign matter.
The surface of plastic parts of Jacky Technology (Dongguan) CO.,LTD is mainly due to excessive burrs. The reason for the excessive burrs of the workpiece is firstly the wear of the die edge. The plastic injection mold components should be re-ground to ensure sharp edges. Secondly, the interval between the convex and concave molds is unreasonable. If the gap is too large, most of the sides are wiped. If the gap is too small, the secondary shear surface will appear. If the hardness of the material is too high, the material should be replaced or the gap should be increased. When the size of the blanking edge is too small or the material to be trimmed is too small, the material will be pulled into the gap of the mold to become a flash. At this point, it is necessary to increase the size of the punched edge or the trimming margin.
Therefore, the general guests come to enquiry JAC-TEC. We can’t provide a quote before we know whether to sell the mold or sell the product. Because the mold is sold to you, JAC-TEC must be responsible for the mold which one is sold. Before the mold moving, the mold is JAC-TEC will definitely improve and provide it to customers with all reports, mold adjustment records, mold repair records, mold maintenance instructions, and more.
Mass production efficiency and cost are highly dependent on the mold. For the failure of the mold in the production process, specific problems should be analyzed and the correct maintenance plan should be formulated. We timely resolution of mold damage, jamming, sharpening and so on quality problems. Dealing with the relationship between mold repair and scrapping can reduce the time for mold-off repair, shorten the production cycle, and ensure the normal production of stamping. JAC-TEC would rather resolve the dispute within the team before moving the mold, and Jacky Technology (Dongguan) CO.,LTD did not want the mold to be unable to function in customer.
