Secondo le materie prime, gli stampi per parti strutturali dell'elettronica di consumo sono principalmente suddivisi in stampi per parti in plastica per ingegneria ABS, stampi per parti in policarbonato, stampi per parti metalliche, ecc. Tra questi, le parti metalliche includono principalmente stampi per parti in lega di magnesio e stampi per parti in acciaio inossidabile. Parti in acciaio. Per molto tempo, i materiali plastici tecnici ABS sono i materiali principali per i componenti strutturali dell'elettronica di consumo, ma i componenti strutturali in plastica di solito hanno lo svantaggio di una scarsa durata. Le parti strutturali in metallo sono affascinate dai consumatori per i loro materiali sottili, il supporto ad alta resistenza, la buona consistenza e la rapida dissipazione del calore. Negli ultimi due anni è stato sempre più utilizzato nei prodotti di fascia alta dai produttori di elettronica di consumo.

Tips on two shot peening die

Multi-color multi-material injection molding refers to combining several plastics into one multi-functional part in one manufacturing process or one production unit. This technology uses multiple materials for injection molding and combines the characteristics of different materials during assembly or other suitable bonding methods to improve the functionality and aesthetics of the product, significantly save costs and provide new designs possibility.

Necessary conditions for two-color injection

The mating material used for two-color injection molding must meet two basic compatibility conditions, namely adhesive compatibility and process compatibility.

Two-color injection molding also sets new requirements for injection molding equipment. For the injection unit, parallel, horizontal and vertical L-shaped and Y-shaped single-cylinder injection structures can be used. For mixing nozzles, special nozzles such as patterns, waves, flow marks, gradients, and intermediate layers can be selected. In terms of clamping, you can choose the standard type, vertical rotation type, horizontal rotation type, rotation axis type, robot rotation type. In terms of feed, in addition to standard hydraulic motor drives, ESD (electric screw drive) charging structures can also be used. For oil circuits, high-speed injection and closed-circuit designs of ACC accumulators are available.

One of the key factors for two-color injection is the variability of computer-controlled programs. Because even for the same type of multi-color product, if you use different mold designs, you must match different electronic control programs. After purchasing a multi-color injection molding machine, if you encounter a new mold design, an excellent multi-color injection molding machine supplier can quickly upgrade existing equipment to meet injection requirements.

New developments in technology

Combined with the observation of two-color injection molding in recent years, in addition to traditional multi-color products (such as automotive lamp molds, air-conditioning panel molds, and TV frame molds), European and American manufacturers have upgraded to several basic molding technologies. Multicolor injection molding field. "Combination" demos, such as two-color molding and in-mold labeling (IML), two-color molding and in-mold assembly (IMA), two-color molding and stack mold (Stack Mold), two Multi-color moldings plus IML plus IMA plus layer mold can complete two-color molding and sandwich injection on the injection molding machine. Therefore, multi-color injection molding technology has attracted more and more attention, and it can not only present multi-color technology.

Multi-color molding technology for headlights

With the development of the national economy, the automobile industry has become our pillar industry. The rapid development of the current automotive industry has put increasing demands on automotive lighting.

The quality of automotive lighting is very important for driving safety, so regulations in various countries around the world have strict requirements for automotive lighting. The design of luminaires should not only meet regulatory safety requirements but also meet other requirements. For example, the appearance should be integrated with the appearance of the entire vehicle, be beautiful and practical, and meet aerodynamic requirements to make the driver and passengers feel comfortable and convenient. Therefore, with the development of the automotive industry, the design technology of lamps is also changing.

Material and process characteristics of the lamp

The lamp usually consists of a base and a lamp housing. The material of the lamp cap is usually a thermosetting material-BMC (bump molding compound). The lamp shell can be made of PMMA, PP, abs, etc., usually two or three colors. In the production process of two-color lamps, special attention should be paid to the injection port of the two-color injection molding machine. The center distance between the two screws should correspond to the center distance of the two injection molds. There are other important points:

Factors Influencing Lamp Stability

1. Two-color injection control unit response: too many switching points, noise interference, unstable command output, and unstable temperature.
2. The noise of hydraulic system: unstable excitation, valve positioning quality, hysteresis, tubing damping changes.
3. Differences in mechanical systems: internal leaks in oil seals, damping, friction differences, screw check valve positioning, anti-reverse effect
4. Uneven plasticization: differences in plasticized products.
5. Mold temperature control.

Countermeasures for car luminescence

1. Carbonization reduces injection pressure, multi-stage deceleration injection, and mold vacuum.
2. The silver pattern completely dries the plastic particles, increasing the back pressure, reducing the melting temperature, and reducing the rate of fire.
3. Bubbles-increase the backpressure, reduce the melting temperature, use a dehumidifier dryer to increase the size of the gate or runner.
4. Bonding line-increase melt temperature, increase filling speed and increase exhaust and mold temperatures.
5. Gross profit-increase clamping force, reduce filling pressure and lower melting temperature.
6. Shrink uniform thickness design, increase pressure and time, and replace the check valve.

Per realizzare un set di due stampi, si può dire che il design rappresenta il 50%. Secondo gli esperti del settore, la gamma di requisiti per il processo di progettazione degli stampi è molto ampia. Oltre a richiedere all'ingegnere progettista di avere una vasta conoscenza della teoria e dell'esperienza degli stampi, è anche importante rivedere e pensare prima di progettare:

Revisione della revisione -Prima di completare la progettazione di due stampi a iniezione, è necessario condurre una revisione della revisione con il cliente e il personale correlato per verificare in modo completo la struttura complessiva della struttura del disegno, la fattibilità e le omissioni dell'elaborazione, sollecitare i commenti del cliente ed evitare errori di progettazione, ecc. Stampi, usati o addirittura rottamati.
