Auxiliary equipment. This includes equipment such as temperature controllers, mold heaters, and cooling equipment that are used to control the temperature of molds and injected material.Â

2. The space in the mode locking region is limited, and it needs to repace with the core after finishing the rotation. The space for mold cavity arrangement and slides in mold are smaller.

Multi-component injectoin molding is also named as the multi color injection molding process, refering to the mateiral that has two kinds of color or more than two used for injection molding through a mold with one or more runners. At first, it is featured by two-color injection molding. Our daily contact is mostly two-color products. For example, the handle of the toothbrush we use every morning and evening are made with two-color injection molding. The common material of handle used is PP (hard glue)+TPE (soft glue). TPE is the best material to blend with PP adhesive coating, and the coating soft adhesive is to improve the grip.

Injection molding is commonly used for producing plastic parts such as automotive components, consumer goods, electronics, medical devices, and packaging.

With the increase of complexity of products, three or four color injection molding needs are more popular. Generally speakingk, the three-color machine has two types, one is two station three-color machine, and another one is three station three-color machine. The difference of them is that they adopt differen turntable control mode according to the sturcure design of products (Two sets of moulds or three sets of moulds).

In this article, we’ll take a look at common factors that influence the cost of injection molding, including equipment, labor, and materials – as well as tips for reducing manufacturing costs.

1.The overmolding injection molding can be divided into 5 types: 1. Type P (parallel double shot), L (right angle double shot), V (sky side double shot), W (oblique back double shot), H (opposite double shot).

Materials. The most common materials used to make molds are steel and aluminum, with steel being more expensive but longer lasting. Overall, the cost of mold materials can range from a few thousand dollars to tens of thousands of dollars.

Injection molding can have high initial costs but is cost-effective for high-volume production. To reduce costs, optimize part design and tooling, select the right materials, and automate your process.

3. Four color injection molding structure is divided into two types: parallel four-color – LV type and back four-color – LVW type.

3C consuming electrics keep seeking improments on the product appearance: small, simple, beautiful, dustproof and waterproof. however, the requirement for this kind of mateiral and procesing normally have clashes, which means it is unable to meet more than one requirement with the traditional design or manufacturing.

How do you optimize part design for injection molding? This complete guide to designing for injection molding provides basic and advanced design tips, including guidelines for creating snap-fits, living hinges and undercuts, and accounting for optimial surface finishes.

Specialty materials. Glass-filled polymers, elastomers, and foamed materials can be used to achieve specific properties in injection-molded parts. The cost of these materials is generally higher than standard thermoplastic materials.

They have different characteristics and customers can select according to their needs. Among them, the V and L types are the most commonly used in Europe. P Type is mostly used in Japan or domesitc made machines. With the five forms of two-color machine, it can continue to derive the definition of the injection form of the three color machine and the four color machine:

When producing parts with injection molding, understanding the range of materials that are available is crucial. Find out more about those materials, their properties, and factors to consider when choosing a material for injection molded parts.

Automation. Automation can help reduce labor costs and increase production efficiency. Consider incorporating automated or semi-automated systems in the production process to reduce labor costs.

Traditionally, it will make the above functions into different plastic parts, and then assemble them together by assembly.

Same for the four-color machine, which can be divided into two station or multi-station & four color machine. Technically, the control precision of multi station rotary table is greatly higher than that of two station. Thus, the manufacting cost of products on this machine is relative high. So, we should select the best option according to the requirements of product structure, like the case of three-color USB flash disk, it is more cost-effective to select multiple stations.

Advantages of multi-shot implant injection molding solutions: it makes one-piece molding and multifunctional integration avaliable, and it supports multi-color modeling without assembly. The key of this technique is the flexible adoptation of bertical injection molding machine. Common machine types include 1 shot x 6stations, 2 shot x 4 stations, 3 shots x 6 stations, among which the multi-station cooling can shorten molding time and increase output. At the same time, it is more convenient to implant injection molding and extract products, and it can achieve automated production.

It can reduce the process of assembly, enhance bonding and improve air tightness by completing plastic (soft/hard), silica gel (solid/liquid), hardware (structure/conductor), electronic chips in a machine cycle.

Injection molding often comes with high initial tooling costs, limited flexibility for small production runs, and material and part design limitations.

1. For the traditional horizontal overmolding machine, the position of the shooting table is fixed, and the shooting table other than the second shooting can only be arranged on the top side and the horizontal side (insert the multi shooting table layout mode). The glue feeding channel interferes with each other.

The costs of injection molding aren’t solely centered on equipment and materials. Like any business or service, there are many moving parts that require oversight and management. Here are a few of them.

Three station is different. The turntable can be positioned at three different positions (120degrees). In other words, the three groups of injection units of the three station &three color machine are respectively injected into three pairs of molds. Therefore, if the boundaries of the three components in the product are adjacent, the three station & three color machine is applicable.

The overmolding is normally featured by two sets of compoents. The half is installed on the fixed mold fixed plate of the overmolding injection molding machine, which is also one side of the injectoin molding gate. Another half is installed on the rotating plate of movable mold, which is the side of mold ejection. The rear molds of these two sets of mold are normally same. The cavity is different. When the first kind of material completes the injectino molding, the fixed and movable molds of injection molding machine open. The rotary plate of the moving die rotates 180 ° with the rear die part of the two molds. Now, do not eject the semi-finished products of the first mold back mold, then clamp the mold before carrying out the injection molding of the second kind of mateiral (during this process, the first kind of material will still be made into semi-finished products in the second mold). After thermal insulation and cooling, the fixed and movable molds are opened. The finished product of the first mold is ejected after moving the mold. This is molding cycle process, in which there will be one semi product and one finished product.

Assembly will also brings a series of difficulities, how to add the fastening structure used for fixing, how to combine soft and hard glue, how to hide the assembly line, how to realize the sealing and waterproof of the electronic part, how to make the logo font more permanent, and how to reduce the assembly manpower.

Tooling refers to the design and manufacturing of the mold or tool used to create injection-molded parts. Here are a few cost-related factors for injection molding tooling.

Mold design. The cost of mold design depends on the complexity of the part being produced, the number of cavities in the mold, and the level of precision required. This can range from a few thousand dollars to tens of thousands of dollars.

The cost of injection molding depends on factors such as part size and complexity, the type of material used, and the quantity of parts being produced. Typically, the larger and more simple the part, and the higher the quantity, the lower the cost per part.
