Plastic Injection Mold China

Plastic Injection Mold China

With the wide scale of packaging, manufacturing and production operations so abundant in the present times, the need for a highly efficient and streamlined system is very essential. For a bulk production of goods many major suppliers need to have the most sophisticated technology available in the market.  This is where plastic mold and injection molding machine come into play. These machines are instrumental when it comes to large scale production of units and have a very wide applicability in a number of industrial sectors like consumer goods, automobile, pharmaceuticals, aerospace industries etc.  So where do these Injection Molding Machine Suppliers come into picture? It is obvious that all these industries are dependent on them to cater to their diverse needs? And keeping in view this rising demand, a lot of suppliers have introduced such injection molding machines with fully automated robots to increase the turnover and tackle the problem of mass production in minimal time.

The first electric tiebarless machine for the injection molding industry has been developed by Engel. The machine was introduced to the plastics industry this summer.

The new Engel e-motion integrates existing tiebarless technology — the capacity to use larger molds in a smaller machine combined with quicker mold changes — with the benefits of an all-electric drive injection molding machine.

According to Kurt Fenske, vice president of sales and marketing for Engel North America, the company has been involved in tiebarless technology for more than 12 years. “Until now, however, the market has forced molders to choose between the advantages of tiebarless and electric. Moving into the electric machine market with our tiebarless offering (was) the next logical step.”

Features of the new e-motion injection molder include:

Tiebarless frame. The frame design is based on the robust, time-tested C-frame of the Engel hydraulic tiebarless, with the following difference: the patented Flexlink mechanical compensation linkage is mounted behind the stationary platen instead of behind the moving platen. This combination of the frame and compensation linkage offers platen parallelism and centricity.
Five-point toggle. The clamp unit includes a high-speed, five-point toggle powered by a servo motor and planetary gearbox which offers longer life and less maintenance compared to a ball screw, Engel says.

Independent drives. Independent, fast-acting servo drives provide simultaneous operation of all machine functions, delivering reportedly faster cycle times and higher molding productivity, the company claims.

CC100 controller. The e-motion uses the same basic CC100 controller as the rest of Engel’s machine line, plus Micrographplus, PD Graphics & Reports and Autoprotect software.

Hot Runner Plastic Injection Mold

Hot Runner Plastic Injection Mold

Hot runner mold can keep the plastic material melting in runner and gate by durative heating. Hot runner system includes  nozzle, hot manifold, temperature controller box, spare parts and so on.

  • What are some advantages of hot runner mold in plastic injection molding process?

1, Shorten the molding cycle time.

Because there is no limit of runner cooling time, the products can be ejector promptly after forming. The cycle time of many thin wall parts which manufactured by hot runner is under 5 seconds.

2, Save the plastic raw material. There is no cool runner in the hot runner system mold, so wasting material will not appear. If the plastic material you use is very expensive, pls choose hot runner for it can reduce the cost of material fee.

3, Expand the application of injection molding process .Hot runner plastic injection mold

Many advanced technology in plastic injection molding developed on the basis of hot runner technology. Such as PET perform, stack mold and so on.

  • What about the maintenance of hot runner mold?

Hot Runner Systems requires a new level of expertise on the part of the mold maker. However, this does not mean that it is too complicated or highly specialized. A well designed system is relatively maintenance-free if it is installed correctly.It can and should happen that tool makers frustrated with these systems and I swear I have too much trouble. This is usually due to the fact that the system is not installed correctly or incorrectly used in the mold.L ‘leading system manufacturers are in support of a well-trained team of specialists to support the proper installation and operation of systems. The time required to listen to these specialists is a good investment!

  • There are several types of hot runner systems?

There are almost as many species are the suppliers! Most have some common characteristics, however. There Sprue gating systems, valve gates, doors peak (most common) and gate edge. Each of the major suppliers candescribe in detail why their system is best suited for your application. Hot runner systems are some of the key components of the form

As a long-term performance

Although an initial investment with hot runner systems, it is easy to justify the long-term benefits. Without increasing the complexity of the design of form, a hot runner plastic injection mold equipped to reduce costs significantly. Because the hot runner is designed and produced independently but at the same time,The times are not affected.Toolmakers should always advise their clients on ways to reduce costs and forms to improve the performance of the mold. His in-depth systems with various runner is a line of common sense shows an active role in supporting the processor down. This in turn increases the likelihood of even more business for mold.

Auto Cover Mold Surface

Auto Cover Mold Surface

Auto cover mold refers primarily covers the engine, chassis, or constitute a cab, car interior surfaces and thin steel plate-shaped parts on the car. Compared with ordinary stampings, cover with a complex shape, the material is thin, high surface quality, good rigidity, large size and the structure is characterized by multi-space surface and so on. Stamping production process generally after blanking (or material under shear), shaping, trimming, punching and flanging and other procedures to complete. Panel forming process mainly drawing (drawing) mainly include local bulging, flanging and bending and other ingredients. In most cases, is the key to the manufacture of such molded parts, it directly affects the product quality, material utilization, production efficiency and manufacturing costs.

About plastic mold material, ordinary mold usually HT300 or HT250; forming part is usually large, mass-produced using MoCr cast iron alloy cast iron or ductile iron, small quantities using HT300; repair if the red part of the material thickness is less than 1.0mm, can be air-cooled steel (7CrSiMnMoV).

Drawing, trimming and flanging is a basic process in which the drawing process is more critical of a process, which directly affects the product quality, material utilization, productivity and manufacturing costs.

Auto Cover mold machining tool types involved in a lot of guides in process, stripper plate, plate slot when the support surface and the ejector holes need to use different diameter flat cutter, corn cutters, end mills, drills and taps and other tools.

The plastics industry is ever expanding, and recently has gotten itself into the auto industry. UPS has recently introduced 150 new trucks, all with plastic  composite bodies, to their fleet on a trial basis in the attempt to cut down on rising fuel costs.

UPS has added the trucks on a trial basis, and has expressed approval of the trucks performance. They have been trying to cut down on rising fuel costs, and the new plastic trucks do a good job of that. The new trucks are a staggering 900 lbs. lighter than the older steel trucks, and have an impressive 40% improvement in fuel economy.

The trucks are also much easier to repair because the plastic composite body panels are modular and can be removed and swapped out if they are damaged. The trucks are also surprisingly durable, which was a concern considering they are made from plastic molds and plastic molding process. They do well in almost any environment, which was also a major concern of UPS because of corrosion damage that trucks operating in wintery conditions where roads must frequently be salted face.
