Dicas sobre dados de dois shot peening

A moldagem por injeção de vários materiais multicoloridos refere-se à combinação de vários plásticos em uma peça multifuncional em um processo de fabricação ou uma unidade de produção. Esta tecnologia usa vários materiais para moldagem por injeção e combina as características de diferentes materiais durante a montagem ou outros métodos de colagem adequados para melhorar a funcionalidade e a estética do produto, economizar significativamente os custos e fornecer a possibilidade de novos designs.

Condições necessárias para injeção de duas cores

O material de combinação usado para moldagem por injeção de duas cores deve atender a duas condições básicas de compatibilidade, ou seja, compatibilidade adesiva e compatibilidade de processo.

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.

Um dos principais fatores para injeção de duas cores é a variabilidade dos programas controlados por computador. Porque, mesmo para o mesmo tipo de produto multicolorido, se você usar diferentes designs de molde, deverá combinar diferentes programas de controle eletrônico. Depois de comprar uma máquina de moldagem por injeção de várias cores, se você encontrar um novo design de molde, um excelente fornecedor de máquina de moldagem por injeção de várias cores pode atualizar rapidamente o equipamento existente para atender aos requisitos de injeção.

Novos desenvolvimentos em tecnologia

Combinado com a observação da moldagem por injeção de duas cores nos últimos anos, além dos produtos multicores tradicionais (como moldes para lâmpadas automotivas, moldes para painéis de ar condicionado e moldes para quadros de TV), os fabricantes europeus e americanos atualizaram para vários produtos básicos tecnologias de moldagem. Campo de moldagem por injeção multicolor. Demonstrações de "combinação", como moldagem em duas cores e rotulagem em molde (IML), moldagem em duas cores e montagem em molde (IMA), moldagem em duas cores e molde em pilha (Stack Mold), duas molduras em várias cores plus IML plus IMA plus layer molde pode completar a moldagem de duas cores e injeção de sanduíche na máquina de moldagem por injeção. Portanto, a tecnologia de moldagem por injeção multicor tem atraído cada vez mais atenção, e não pode apenas apresentar a tecnologia multicor.

Tecnologia de moldagem multicolorida para faróis

Com o desenvolvimento da economia nacional, a indústria automobilística tornou-se nosso pilar da indústria. O rápido desenvolvimento da atual indústria automotiva colocou demandas crescentes na iluminação automotiva.

A qualidade da iluminação automotiva é muito importante para a segurança ao dirigir, portanto, os regulamentos em vários países ao redor do mundo têm requisitos rígidos para iluminação automotiva. O design das luminárias não deve apenas cumprir os requisitos regulamentares de segurança, mas também outros requisitos. Por exemplo, a aparência deve estar integrada à aparência de todo o veículo, ser bonita e prática e atender aos requisitos aerodinâmicos para fazer o motorista e os passageiros se sentirem confortáveis ​​e convenientes. Portanto, com o desenvolvimento da indústria automotiva, a tecnologia de design das lâmpadas também está mudando.

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.
