Description of the invention: [Technical field to which the invention pertains] The present invention is a comprehensive technique for the use of an effective control of the woven fabric and the effect of a good encapsulation effect. The method of coating. [Prior Art] With the evolution of technology, the encapsulation technology for products, especially electronic products, has also been continuously innovated to enhance surface treatment technology. * Generally speaking, 'for the purpose of achieving enthusiasm and beauty, therefore, the rubber coating technology, the commonly used coating method, including: directly sprayed on the surface of the material to be coated with rubber paint, using a sticky rider bag Glue material _ on the storage wire of (10). '_, Lishe said that the two types of plastic products formed by the two types of financial, (4) thermal expansion and contraction or wet money scales caused by insufficient adhesion and resulting in succession phenomenon. S, the current process of the process of the process of the major steps: a Γ - use the mold to form the material; - the material to be coated in the concave hole of the mold; - at high temperature to introduce the plastic material in the mold and the material to be coated In between the recessed holes; - Loose the encapsulated component from the recessed hole. This process is often used to encapsulate various electronic components. Generally, the rubberized material is a rubber material, and the material is a polymer bribe, such as ABS. (aeiyl. bell e butadiene styrene). The encapsulation process is carried out by soft (4) coating on the hard type, and the secret coating area is different. Therefore, it is necessary to open and set separate molds, first in the first After the return, the plastic parts are placed in the first set of fields for encapsulation. The way of placing the clothes is tight fit. The tightness of the hold will affect the yield. Generally speaking, the catch is loose. It is convenient for the molding personnel to work, but the yield is low, if the locking is tight, the forming personnel are less likely to work, but the yield is higher. The disadvantage of the above method is that two sets of molds are used, because each has a tolerance value. , so the yield and fine 801-A31088TWF (5.0) 5 i 1271 298 degrees directly depends on the mold factory technology and the experience of shooting waste, in addition to the poor molding surface, or _ air rm wear resistance is easy to be scratched; in addition, if the rubber and plastic adhesion is poor, more tear off and so on Poor degree _. In summary, the rubber wins 2 degrees lower and the more the axis type, the outside is also, if the mold temperature is increased, the nuclear wealth will be improved, and if the hunting is done by the cold water cooling department, the molding situation can be improved. However, the entire process time has to be lengthened. 7 If the shape variables generated by the fusion of two different materials are needed, it is necessary to look at the process of the surface process, the accuracy of the machine, the molding, and the inspection. Adjustments are made. In order to form a fully coated package, in addition to the above-mentioned process factors, if the surface of the molded transfer piece is to be fully covered, it cannot be directly recorded by the surface, and the momentum of the ride is corrected. The fixing of the miscellaneous tools is also the result of the problem. The development of a kind of encapsulation technology that can effectively achieve a comprehensive encapsulation effect is one of the main directions of the industry. [Inventive content] The object of the present invention is to provide a A fully encapsulated encapsulated molded article and a method of forming the same to provide a comprehensive coating method for effectively controlling process conditions to achieve a good encapsulation effect. In order to achieve the above object, the present invention provides a method for forming The method of fully coating the encapsulated molded article uses a material changer to form a polymer material; the polymer material is taken out and placed under a degree of 15-30 hours to stabilize the size of the polymer material; The molecular material is placed in a plastic mold with a concave hole; at the injection temperature of the chick 2i〇〇c, the injection speed (10) is emitted from the knife segment and the master-hardness 7〇·9() α is charged in the package. The recessed hole plastic mold 0801-A31088TWF (5.0) 6 1271298 has a medium 'to make the rubber-filled material fill the concave hole and cover one surface of the polymer material to form a rubberized layer' The material is a thermoplastic elastomer (TPE); the rubberized material is hardened. And, the encapsulated polymer material is taken out from the rubber mold and subjected to a cooling step to obtain a fully coated rubber molding. In order to achieve the above object, the present invention further provides a fully encapsulated encapsulated molded article, comprising: a polymer material; a coating layer covering at least one surface of the polymer material, the adhesive layer being a Thermoplastic glue he _ 〇 1) 1 off ^ 1_11 ^ 11 > £). And an inter-melting layer is formed between the polymer material and the encapsulating layer by melting the polymer material and the encapsulating layer.
