Zink dan Aloinya

Zinc and its alloys are commonly used in precision casting, characterized by good fluidity, a low melting point, and excellent corrosion resistance. Zinc alloys enable precise filling of complex molds during the casting process, making them suitable for parts requiring high precision and excellent surface quality. Zinc alloys are widely used in the electronics, automotive, and consumer goods industries, often in the manufacture of housings, connectors, and auto parts.

In precision casting, zinc alloys are primarily used in die casting and investment casting processes, offering high precision and high production efficiency. Their low melting point helps reduce production costs, and their excellent surface finish properties give them significant advantages in high-volume production.

Zinc and Its Alloy Casting Process

Pemutus Pelaburan

Applicability: Suitable for casting zinc and its alloys, but is generally used for precision castings, especially when high precision and complex geometry are required. Investment casting can achieve very detailed designs, including complex internal cavities and precise surface finishes.

Advantages:
· High-precision, low-volume products: Small precision parts in the aviation, automotive, and medical device industries.
· Excellent surface finish: Suitable for zinc alloy parts with complex shapes, thin walls, and high wear resistance.
· Rapid development and customization: Customized products requiring fast delivery.

Tuangan Pasir

Applicability: Sand casting is a traditional and widely used casting process suitable for zinc alloy casting, especially in the production of larger castings. Sand casting molds are relatively low cost, suitable for small or medium batch production, and can produce larger castings.

Advantages:
· Medium-sized, non-precision castings: Suitable for larger, simple-shaped parts such as automotive components and electrical enclosures.
· Lower costs: Suitable for high-volume production where cost-effective products are required, especially in high-volume production.

Die Casting

Applicability: Die casting is very suitable for the efficient large-scale production of zinc and its alloys, especially for the mass production of high-precision and thin-walled castings. Zinc alloys have excellent fluidity and low melting points during the die casting process, making them very suitable for the rapid production of high-quality castings.

Advantages:
· Large-Scale Production and Precision Castings: Suitable for mass production of high-precision, complex-shaped castings, such as electronic device housings, home appliance components, and automotive parts.
· High Production Efficiency: Suitable for industries with demanding lead times, such as consumer electronics, automotive, and industrial equipment.

Percetakan 3D

Applicability: 3D printing technology is suitable for small-batch, high-complexity, and rapidly developed castings, and is particularly suitable for customization and prototyping. Although 3D printing casting is still in its development stage, in some cases, it can be used to produce complex zinc alloy parts.

Advantages:
· Small-batch customization and rapid prototyping: Zinc alloy parts that require rapid production, such as prototype testing and design verification.
· Complex shapes and innovative designs: These applications require complex castings, especially those requiring rapid modification and verification during the design phase.

Soalan Lazim

S1. Adakah anda sebuah syarikat perdagangan atau pengilang?

Kami adalah sebuah kilang dengan lebih 20 tahun pengalaman dalam tuangan dan pemesinan. Kami mempunyai kepakaran yang kaya dalam industri ini. Jika anda menjumpai pembekal yang mendakwa menghasilkan tuangan dalam pelbagai jenis bahan (seperti keluli, besi, keluli tahan karat, tembaga, dll.), mereka berkemungkinan merupakan syarikat perdagangan. Jika anda melihat bengkel secara aktif mengeluarkan alat ganti, anda boleh yakin bahawa kami adalah pengeluar tulen.

S2. Bolehkah anda memetik berdasarkan lukisan 3D?

Ya, selagi kami menerima fail CAD atau model 3D yang serasi yang boleh dilihat dengan perisian seperti Petikan Pertama atau penyemak imbas Firstcut, kami boleh memberikan sebut harga. Sila ambil perhatian bahawa lukisan 2D sahaja tidak mencukupi untuk pembuatan komponen ketepatan.

Kami menyokong model CAD 3D daripada SolidWorks (.sldprt), ProE (.prt) dan sistem CAD lain, biasanya dalam format IGES (.igs), STEP (.stp), ACIS (.sat), atau Parasolid (.sat).
