For providing better service,YK bought a 200T vertical injection machine in June,2018.It could put the inserts tool in size 700*750*650.
1.Mold supplier should use standard base（such as LKM) or similar quality base, The material of the mold base can be used 45# steel, （45# imported steel from Japan）, P20 and so on, and mold supplier should ensure the enough strength. 2.Core and cavity azimuth need be in accord with mold base, supplier should guarantee the mold drawing is accordance with actual mold. 3.Core and cavity need be marked with used material and its hardness, each mold need have its own BOM. When transfer mold, suppliers need provide detailed 2D and 3D drawings, and injection parameters. If hot runner system included, supplier also need attach relevant drawings and introductions. 4.Cooling system should be marked IN and OUT accordingly to its cooling liquid inlet and outlet, connection standard is that M12 water nozzle matches 10mm water pipe. water nozzle from two sides of mold need be outside, from up and down sides need be inside. 5.Location ring should be unified as diameter 100mm. 6.Holes of ejectors of mold base should be φ35mm, ejectors are φ30mm. Molds which are used in below 150T machine need have 3 ejector holes, and these holes are arrayed vertically, if else, molds need have 5 ejector holes arrayed like five-pointed stars. 7.Counting device should be installed beside parting line. Molds with slides and lifts should have return mechanism and enforce return pins. 8.Each plates of mold should be manufactured with eyebolt hole, and marked its diameter dimension. 9.All mold cores need have inserts, push blocks and located blocks. 10.Each mold should have its ID. 11.Mold with hot runner system should have thermal baffle installed on top to prevent from being heated.
Process Start-Up (Optimizing Fill, Packing and Other Parameters) The following procedure works well for any velocity-controlled injection molding machine. The following conditions, although generally applicable, are not necessarily optimum for a specific application.
Plastic Injection molding is one of the most popular manufacturing processes for making thermo plastic products and mold design is a key aspect of the process. Design of molds requires knowledge expertise and most importantly experience in the field. When one of these is lacking selection of an appropriate mold for manufacturing a plastic component is done on a trial-and-error basis. This increases the cost of production and introduces inconsistencies in the design. This paper describes the development of an intelligent mold design tool. The tool captures know ledge about the mold design process and represents the knowledge in logical fashion. The knowledge acquired will be deterministic and non-deterministic information about the mold design process. Once developed the mold design tool will guide the user in selecting an appropriate mold for his plastic part based on various client specifications.
Mold industry is an important part of China's hardware industry, the five-second period is the proper response to major changes in the development of our domestic and international environment
Moldmaker finds success with U.S. engineering, Chinese manufacturing model
Sprue bushings are available in more than a dozen different types and styles. Most mold designers select the “B” series bushings because the 7/8-in. head thickness is often the same thickness as the injection clamp plate and it works nicely with standard locating rings. Then they select the nozzle seat radius, one of the four available orifice sizes, and the overall length. That’s often the extent of the consideration given to the sprue bushing during the mold-design phase.
Counterfeit mold components and systems from foreign manufacturers, especially those in China, that are not in compliance with industry standards and specifications have long been a problem. Progressive Components, a production mold component developer and distributor in Wauconda, IL, has a solution. Its new Component Certification program is said to offer visibility of supplier component purchases and verification of mold specification compliance.
SABIC’s Innovative Plastics business announced on April 23 that it is proceeding with an investment in a production line for STAMAX long glass fiber-reinforced polypropylene (LGFPP) at its manufacturing site in Shanghai, China. The new capacity, expected to come onstream during the second half of 2015, brings SABIC’s STAMAX operations closer to customers in China and Asia-Pacific and responds to increased demand for the lightweight LFGPP material from automakers in the region.
What started out as a routine request from one Plastics Technology columnist to another to review a draft for an upcoming article led to five highly experienced industry professionals collaborating to create this article about something virtually every molder does every day—sometimes many times a day—mounting a mold in a press.
Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts. A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section. Injection molding is used to produce thin-walled plastic parts for a wide variety of applications, one of the most common being plastic housings. Plastic housing is a thin-walled enclosure,often requiring many ribs and bosses on the interior. These housings are used in a variety of products including household appliances, consumer electronics, power tools, and as automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well.
Malfunction law research is favorable for development of maintenance measures, as well as to establish a scientific system maintenance. When injection molding machine is in use, its performance or status will gradually decline as the time goes on. There will be a lot of malfunction before some of the warning, which is called a potential malfunction, which can identify the physical parameters indicate that a functional failure is imminent, the functional breakdown shows that machine is disabling the specified performance standards.
