Reasons For Failure Of Demoulding And Treatment Methods (1) The runner is too large to modify the mold; (2) The runner cooling is not enough to extend the cooling time or reduce the temperature of the tube; (3) The mold release angle is not enough to modify the mold to increase the angle;…
DetailsInjection Molding Machine Special Robot Classification For the robots used in injection molding, they can generally be divided into the following three types according to their functions: 1. Simple injection molding robot Simple injection molding robots can be divided into fixed mode program type and variable program type. Fixed-program injection molding machine manipulators cannot change…
DetailsFinished Mucous Membrane, Difficult To Demould Depending on the size and temperature of the molded product, when the mold release resistance is increased, mold release failure occurs. Although it is also affected by resin characteristics and molding conditions, the main reason is the shape of the molded article and the structure of the mold. Of…
DetailsType Of Plastic Molding 1.Injection molding The plastic material is first melted in a heating cylinder of the injection molding machine, and then a method of forming the melt by a reciprocating screw to push the melt into a cavity of the closed mold. It can not only produce high-precision, high-quality products under high productivity,…
DetailsPlastic Properties (1) Easy to process, easy to manufacture (easy to mold) Even if the geometry of the product is quite complex, it can be easily produced as long as it can be released from the mold. Therefore, its efficiency is far better than metal processing, especially injection molding products, through a process, can produce…
DetailsKey Points For Test Mode When we received a new mold and needed proofing, we were always eager to try out a result earlier and pray for a smooth process to avoid wasting work and causing trouble. But here we must remind two points. First, the mold is inspected on the mold as soon as…
DetailsHow To Properly Use And Repair Aluminum Extrusion Dies The life of aluminum extrusion die has become the main bottleneck in the development of aluminum profile industry in China. The design and manufacturing cost of aluminum extrusion die accounts for about 20% of the total production cost. It is one of the key technologies for…
DetailsThe Cause Of Swelling Or Bubbling In Injection Molded Products Some plastic parts quickly swell or swell on the back of the metal insert or in a particularly thick part after the mold is demolded. This is because the plastic that is not completely cooled and hardened is caused by the release of gas under…
DetailsAnalysis Of The Causes Of The Shock Pattern Of Injection Molding Products Rigid plastic parts such as PS form dense ripples on the surface near the gate, centered on the gate, sometimes called a shock pattern. The reason is that when the melt viscosity is too large and the mold is filled in a stagnant…
DetailsNew Mode Test Steps And Actions 1. Before testing the mold, first check whether the mold is assembled and whether the raw materials are dried. 2. Before the mold change, the mold spray rust inhibitor in the production is to be placed in the mold, replace the mold and return to the position and fill…
