Characteristics Of Insert Molding | شركات صب حقن البلاستيك في الصين مع صناع يموت صب الأدوات والحقن

إدخال القوالب هو طريقة صب للمنتج المتكامل عن طريق حقن الراتنج في الإدخالات غير المتشابهة المعدة مسبقًا في القالب, ويتم ربط مواد الانصهار وترسيخها بالإدخالات.

يشير قولبة SERT على الركيزة إلى طريقة تضمين أجزاء القولبة بالحقن على سطح اللوحة المعدنية.

طريقتا الصب هما في الأساس نفس الشيء. خصائصه على النحو التالي.

1. مركب من قابلية تشكيل الراتنج, خاصية الانحناء وصلابة المعدن, strength and heat resistance can make a complex and exquisite metal plastic integrated product.

2. خصوصاً, the combination of insulation and metal conductivity of resin can meet the basic functions of electrical products.

3. The pre forming combination of multiple inserts makes the post engineering of product unit combination more reasonable.

4. The embedded products are not limited to metal, but also have cloth, paper, الأسلاك, بلاستيك, زجاج, خشب, coil, electrical parts and so on.

5. For the rigid molding products and the bending elastic molding products on the rubber sealing pad, the integrated products are made by injection molding on the base, which can save the complicated operation of arranging the sealing rings, making the automatic combination of the later process easier.

6. Because of the fusion of the material and metal insert, compared with the press in molding method, the metal insert gap can be designed to be narrower.

7. The proper resin and forming conditions are selected, العوامل الهيكلية التي يجب مراعاتها في تصميم قوالب حقن البلاستيك, for products (such as glass, coil, electrical parts, إلخ.) which are easy to be pressed and damaged, they can also be sealed and fixed by resin.

8. The inserts can also be completely sealed into the resin by selecting the appropriate mold construction.

9. After the insert is formed, the product with hollow groove can be made after core removal hole treatment.

10. The combination of vertical injection molding machine, manipulator, and whole line of insert products can realize automatic production in most of the embedded parts forming engineering.

Considerations for design and selection of automatic insert forming system

1. The metal insert is easy to produce uneven shrinkage. The limit test of shape and dimension precision of important parts should be done in advance.

2. The metal insert is easy to deform and shift during injection. The mold composition and the design of mold shape which is easy to maintain the metal insert should be fully considered. For the products whose shape cannot be changed, the prior test is indispensable.

3. When the conveyor is used for the separation of metal inserts, the contact between metal inserts and the insert and vibration ball will cause slight damage to the surface of the insert, which will affect the product quality. The allowable limit range of quality shall be confirmed in advance.

4. The serration, انفتل, material thickness difference, diameter difference and thickness difference caused by gold deposit processing should be measured in advance. On this basis, the design of the matching selection and mold structure of the automation device is carried out.

5. The predictable problems restricting mold construction such as gate position and forming period are solved in advance or corresponding improvement measures are available.

6. It shall be confirmed whether the metal insert needs preheating or drying treatment. The purpose is to ensure the quality of products and the stability of forming.

7. All kinds of testing devices set in the mold are used to ensure the stable forming action under the influence of the mold heating, force, vibration and other environmental conditions. It should be confirmed whether to use it.

8. In order to avoid the small pieces of metal inserts and molding products piled in the mold cavity, the air blowing device can be assembled if necessary.

9. Because of the high investment price of system equipment, it is necessary to consider whether the production capacity of equipment can be ensured before using. When using special machine, it is necessary to ensure that the products can be continuously produced without form updating in several years.

10. When using general machine, it is necessary to confirm how many kinds of products and few batch inserts have combined production. If the overall production cannot be guaranteed in large quantities, it is difficult to recover the fixed assets of each product. في هذه الحالة, it is necessary to replace some devices to meet the requirements of variety renewal in a certain range.

11. The factors and technical decisions such as the accuracy of metal inserts, the shape of inserts, whether the mold is conducive to the shape of the inserts and the shape of the molded parts, إلخ., which determine the molding rate, production and forming cost conditions of the inserts.

12. The key to the automatic insert forming system is the effective combination of injection machine, mold and automation device and how to play its functions in a short time. Please consult with the manufacturer with considerable practical experience to choose
