DGMF Mold Clamps Co., Ltd mainly offers a wide range of Mold Clamps and Mold Components. Used in processing machinery especially on plastic injection molding machines, and pressure dies casting machines.

Plastic injection molding refers to the manufacturing process used to produce a large volume of identical parts. With large scale injection molding, manufacturers can produce parts of a variety of sizes and shapes, including small and large part molding. Injection molding is extremely versatile and has several advantages when compared to other plastic molding methods.

Also, there are two barrels 1 and 5, and the nozzle structure is a little special. In addition to the normal nozzle function, it can also be rotated by gear 3 attached to the rear.

This type of molding process, also commonly referred to as two-component injection molding, is usually completed with a set of molds and requires a special two-color injection molding machine. Generally, there are the following requirements:

During molding, after the melt is plasticized in the barrel, open/close valves 2 and 4 control the order of the melt entering the nozzle and the proportion of material discharged, then the nozzle is injected into the mold cavity increase. Various plastic injection molding products with different color mixing effects can be obtained.

Double Injection, sometimes known as 2 material 2 shot molding or 2K molding, is an innovative manufacturing process used to produce complicated molded parts from two different materials.

There are two barrels, and the structure and usage of each barrel are the same as a normal injection-molded barrel. Each barrel has its own passageway that connects to the nozzle, and on-off valves 2 and 4 are also attached to the nozzle passageway.

Two-color mold: A mold that injects two plastic materials into two molding machines with the same injection molding machine, but the product is injected only once.

There must be a constant temperature difference between the melting points of the two materials. Normally 60 ° C is recommended, and at least 30 ° C is recommended. The material of the first shot has a high melting point temperature. Usually, the first shot is a PC. Or on PC / ABS, the second shot is TPU or TPE. , PC thickness is 0.6-0.7mm, the software is over 0.4mm.

Matching materials for two-shot injection molding must meet two basic compatibility requirements: adhesive compatibility and process compatibility.

Transparent and opaque dual shot design for decoration: the first shot is an opaque material, the second shot is a transparent material, the opaque material is usually hot PC, the second shot transparent material is PMMA or PC. Your PC should be sprayed with UV to protect it. PMMA can be UV or enhanced. If there are letters on the surface, you need to select UV.

Lerner Molded Plastics has a reputation as a top-quality provider of injection molding services for customers in a variety of industries. Their ISO certified, state-of-the-art facility produces injection molded components from a wide range of plastics.

Today, we talk about the 2K injection molding technology, a molding method in which two different colored plastics are injected into the same mold.

Lerner offers complete supply chain services, including local sourcing of all raw materials, sub-assembly components, packaging, warehousing of finished products, and direct drop ship capabilities.

Small lens double shot design: The first shot is opaque, the second shot is the lens, the first shot is as high as possible and the second shot is PMMA.

Lerner provides quality OEM, automotive, and consumer products. Lerner specializes in manufacturing single, co, and tri-extruded plastic profiles, pipes, and tubes. Applying a combination of materials to meet the requirements of flame-retardant and food-grade applications. Lerner’s facility can accommodate anything from prototypes to high-volume runs.

During molding, different colored melts are plasticized in barrels 1 and 5, gear 3 rotates the rotating shaft 4, and different colored melts alternately enter the mold cavity to obtain different colors and colors. A patterned plastic product that radiates from the center to the periphery.

Lerner Molded Plastics provides mold design services for injection molding, blow molding, rotational molding, thermoforming, and extrusion. Their capabilities include anything from small precision tools to large, single-cavity tools.

As a provider of blow molding services, Lerner Molded Plastics offers equipment in single or dual head configurations with up to a 40-lb. capacity. Their shuttle press systems are utilized for high-volume production, and their capabilities can accommodate components that feature multiple cavities in various sizes.

You can improve the practicality and aesthetics of plastic parts by displaying them in two different colors, or by displaying regular patterns or irregular moire-like patterns on plastic parts.
