2K injection molding

2K injection molding

Connexions has more than 20 years experience in injection molding industry. With strong engineering design team and advanced machines, we can provide custom 2K injection molding and plastic injection moulding services for all industries.

2K injection molding is also called 2k mold, two-shot Molding or double injection molding. It is a cost-effective method to produce plastic parts with two or more colors moulded at the same time, such as Radio control buttons, Dashboard faceplates, Toys with movable parts, Flexible hinges, Parts with seals molded in, Soft grip handle inserts, Automotive A/C or heater louvers.

FAQ

Q1: What’s 2K Injection molding?

A: An innovative method of producing molded parts from 2 totally different materials known as 2K molding, double injection molding, or 2 shot molding.

In this type of moulding two materials with varying properties, colors and hardness are molded together in one composite end product. This process is cost effective. Material selection is key factor for 2k molding. It is used for large scale production.

In 2k injection molding it is possible to perform more operations on the polymer while it is flexible and hot. And different materials can be used to formulate a high quality end product.

Q2: What’s the advantages of two shot injection molding?

A: In this method one or more injection are used separately to inject plastic into mold. The material is separated very precisely on the basis of hardness and color. It is Cost effective and efficient and can produce high quality molds All types of custom based products can be made on demand.

Q3: What’s the Disadvantages of two shot molding?

A: On introduction of this process the cost are too much high as heavy 2k injection machines are needed for molding.

Q4: What’s the process of 2K injection molding?

A: 2K injection molding is two-component molding or two-color injection molding. It is realized on a two-color injection molding machine. One material is injected into a product, and then the mold is flipped on the two-color machine to jump to another injection molding barrel corresponding to In the cavity of the mold, the part is used as an insert, and another material is injected on it to form an integrated dual-material product. The injection molding machine has double barrels and double mold cavities. During the injection molding process, products of both materials are produced at the same time, but the products of one cavity will enter the next cavity as an insert.

Q5: Are you trading company or manufacturer ?

A: We are a manufacturer specialized in plastic injection molding with more than 20 years of experience.

Q6: What is the production lead time for producing 2K injection molded products?

A: The production time depends on various factors, such as mold sizes, injection mold cavity numbers, shot period, and and so on. Normally, the lead time is 15-25 days. Connexions can guarantee that we will make every effort to meet your requirements of timeline.

Q7: How long does it take to have the first samples of plastic injection molding parts?

A: The first sample will be available once the plastic injection mold is completed. We will sent the sample to you via express service (FedEx, DHL or UPS). Normally, it will reach you within 3-5days.
