Embodiment 1

[0055] Example 1: PC+20% CF&PC+50% GF co-injection molding

[0056] The first part adopts the first material (PC+20% CF) plastic pellets to be heated to 280-290 degrees, and is injection-molded on an injection molding machine equipped with a mold.

[0057] At the end of the injection of the first part, the high-rigidity plastic material PC+50% GF in the sub-injection station is delayed injection molding the second part from the sub-injection port in the same set of molds, and the two-material co-injection can be obtained. The product.

[0058] The products required by customers can be obtained through appearance treatment. Appearance treatment can be carried out by means of in-mold decoration (IMD: In-Mold Decoration), painting or out-mold decoration (OMD: Out Mold Decoration).

Embodiment 2

[0059] Example 2: PPA+20%CF&PPA+50%GF co-injection molding

[0060] The first part adopts the first material (PPA+20% CF) plastic pellets to be heated to 290-320 degrees, and is injection-molded on an injection molding machine equipped with a mold.

[0061] At the end of the injection of the first part, the high-rigidity plastic material PPA+50%GF in the sub-injection station is delayed injection molding the second part from the sub-injection port of the same mold, and the double-material co-injection can be obtained. The product.

[0062] The products required by customers can be obtained through appearance treatment, which can be done by painting or OMD (Out Molding Decoration).

Embodiment 3

[0063] Example 3: PPS+20%CF&PPS+45%GF co-injection molding

[0064] The first part adopts the first material (PPS+20% CF) plastic pellets to be heated to 300-320 degrees, and is injection-molded on an injection molding machine equipped with a mold.

[0065] At the end of the injection of the first part, the high-rigidity plastic material PPS+45%GF in the sub-injection station is delayed injection molding the second part from the sub-feed port in the same set of molds, and the double-material co-injection can be obtained. The product.

[0066] The products required by customers can be obtained through appearance treatment, which can be done by painting or OMD (Out Molding Decoration).

[0067] Please refer to Figure 4 , Figure 4 It is a schematic diagram showing the product structure of a preferred embodiment of the present invention.

[0068] In order to achieve the above object, the double-material combination product of the present invention is a product formed by the ...

Abstract

The invention discloses a two-material bonding apparatus, a two-material bonding method and a two-material bonding product. The two-material bonding apparatus comprises: an injection molding machine,wherein the injection molding machine has a main injection table and a sub injection table, and the main injection table and the sub injection table are used for respectively injecting a first material and a second material to mold the first component and the second component of a product; a mold having a main material inlet and a sub material inlet, wherein the first component and the second component are molded in the mold and are directly combined into the product; and a mold temperature variable controller, wherein the mold further has a timing controller. The two-material bonding method comprises that the main injection table of the injection molding machine injects the first material into the mold through the main material inlet of the mold to mold the first component; the injectiontiming is controlled by the timing controller of the mold, and the sub injection table of the injection molding machine injects the second material into the mold through the sub material inlet of themold to mold the second component; and the first component and the second component are directly combined to form the product. The product is molded through the method. With the method and the apparatus of the present invention, the cost and the working time are saved, the appearance of the product is good, and the yield of the mass production is improved.

Description

【Technical field】 [0001] The invention relates to a double-material combining technology, in particular to a double-material combining device, method and product thereof. 【Background technique】 [0002] People are increasingly pursuing high-quality life, and the pursuit of products pays more and more attention to its shape and appearance decoration effect. The development of products now requires thinness and high rigidity at the same time. Therefore, the current development trend of casing products in the 3C industry is to develop in the direction of thinner, lighter and stronger. For example, Ultrabook ultrabooks and business models begin to use high-rigidity fiber-reinforced composite materials (such as glass fiber GF content 40-55%; carbon fiber CF content 20%) to achieve ultra-thin and lightweight. [0003] When producing plastic products, two different materials are often combined to form a product, so the Insert Molding (embedded molding or embedded molding) process...
