Basınçlı Döküm Ürünleri İmalat Hizmetleri

Yüksek basınçlı döküm nedir (HPDC)? Yüksek basınçlı döküm Ürünleri süreci nasıl çalışır??

Yüksek basınçlı döküm prosesinde, erimiş metal veya metal alaşımı kalıba yüksek hız ve yüksek basınçla enjekte edilir.

Yatay yüksek basınçlı döküm makineleri kalıbın tamamen kapalı olmasını sağlar. Uygulayabilecekleri sıkma kuvveti miktarına göre sınıflandırılırlar ve 550 ile 5700 ton.

Manufacturing for Sie-Casting Products

Kullanılan metale bağlı olarak, Kalıbı dolduran enjeksiyon ünitesi sıcak oda veya soğuk oda olabilir. Sıcak kamaralı basınçlı dökümde, metal basınçlı döküm makinesinin içinde tutulur, daha sonra hazneye çekilir ve enjeksiyon pistonunun hareketi onu kalıba sokar. These parts of the machine are always in contact with molten metal.

Soğuk oda sürecinde, metal önce ayrı bir fırında eritilir ve bir bekletme fırınına aktarılır; daha sonra doldurma haznesine dökülür ve kalıba enjekte edilir. KANGDING offers a wide range of cold chamber high pressure casting machines.

Advantages of the high pressure casting process

High pressure casting technology can produce very large alloy parts in high volumes and at high speed.

These machines produce light alloy parts with great precision, superior surface finish, excellent uniformity and optimal mechanical properties.

The high-pressure casting process can also produce thin-walled components and cast parts together with different types of parts, such as screws and liners, which are then an integral part of the product itself.

Cold chamber die casting.

In the cold chamber process, the melting of the metal is carried out in furnaces outside the machine, and the injection chamber is at a temperature lower than that of the casting of the alloy.

In cold chamber injection molding, the molten material is fed from an external melting pot or furnace to the injection chamber (either manually or automatically), where a hydraulically operated plunger pushes it into the mold. Injection machines are equipped with hydraulic and pneumatic circuits, and controlled by automatons in such a way that they can be programmed to carry out the injection process autonomously.

The cycle speed is fast and high pressures are reached during the process. All castable metals and alloys, alüminyum, bakır, pirinç, magnezyum, çinko, vesaire. can be injected.
It is necessary to synchronize the filling of the chamber with the closing of the mold, so that when the mold closes, the injection can be carried out immediately, preventing the cycle from being delayed and also preventing the material from cooling down.

Vertical cold room. The compression chamber and the entire injection mechanism are arranged in a vertical position. At the initial moment, the lower piston covers the mold nozzle, while the working or upper piston is in its upper position. Sonraki, the upper piston, hydraulically actuated, moves downwards with a certain adjustable speed (injection speed), and when it comes into contact with the metal, the lower piston also begins to move downwards, uncovering the nozzle from the mold. . The upper piston continues its race until the metal completely fills the cavities of the mold including the funnel and the runners, leaving a portion of the metal in the chamber. Sonraki, both the upper piston and the lower piston rise to remove the excess solidified material.

Aluminum alloy castings

There are two types of cold chamber machines:

Horizontal cold chamber The filling chamber is arranged in a horizontal position. The piston advances by closing the intake port and injecting the metal into the mold. The metal fills all the cavities and the piston remains in its forward position, maintaining pressure until complete solidification of the metal. When the two halves of the mold are opened, the piston continues to exert pressure on the solidified riser to help the part come out.

Başvuru

Cold-chamber high-pressure casting technology is ideal for the production of a diverse range of aluminum and magnesium parts for the automotive industry, such as engine blocks, gearbox crankcases, oil pans, engine mounts and structural parts. like the cross beams.
It is widely used in other industries to manufacture components for applications ranging from the simplest (a lighting component) to the most demanding (parts for an aerospace engine).
