Advancing Precision Die Casting With the A3 Series

Dynacast's commitment to precision, innovation, and quality drives everything we do. One of the pillars of this commitment is our proprietary multi-slide technology, which enables the production of complex, high-quality metal components with exceptional accuracy and efficiency.

While our A2 machines have long been recognised for their speed and precision, the A3 die casting machines push performance even further, offering enhanced versatility, larger die capacity, and improved cycle times. This article explores the A3 SIS and A3 MAG SIS models and how they're setting new standards in small-part metal and magnesium die casting.

A3 Machine Capabilities

Dynacast's A3 machines are designed to deliver high-speed production, tight tolerances, and consistent quality, even in the most complex geometries.

Our multi-slide technology enables faster cycle times by allowing multiple slides to operate independently, significantly improving the efficiency of part ejection and mould filling. This results in:

•  Shorter production cycles
• Fewer secondary operations
• Reduced material waste
• Greater design flexibility

The A3 platform is ideal for industries requiring precision micro-components, such as automotive electronics, telecommunications, medical devices, and consumer products.

A3 SIS: Superior Injection System for Enhanced Productivity

Introduced in 2010, the A3 SIS (Slide Injection System) machine was engineered for greater speed, strength, and reliability. It features a reinforced main plate with 28 tons of locking force, providing the stability needed for precision casting.

Key Specifications and Features:

• Die size: Up to 160 x 140 mm
• Shot weight: Up to 180 grams
• Locking force: 28 tons
• Slides: Supports four slides plus additional integrated options

The SIS injection system offers several competitive advantages:

• Faster cycle times: Rapid injection and cooling enable higher output areas.
• Higher cavity capacity: Produces more parts per cycle, improving efficiency.
• Improved surface finish: Reduces porosity and enhances surface quality.
• Complex part design capability: Multiple slides allow intricate geometries and undercuts.

The A3 SIS is ideal for zinc and aluminium alloy components where surface finish, precision, and consistency are essential. 

A3 MAG SIS: Precision for Magnesium Alloy Components

The A3 MAG SIS builds on the proven foundation of the A3 SIS, but it's specifically engineered for magnesium die casting applications. It includes a two-chamber melting pot designed to handle magnesium's unique properties safely and efficiently.

Key Benefits and Features:

• Dedicated magnesium system: Ensures safety and compliance with CE safety standards.
• Two-chamber melting pot: Enhances temperature control and casting consistency.
• No machining required: Produces net-shape or near-net-shape components.
• Superior part quality: Enables thinner walls, tighter tolerances, and minimal porosity.
• Optimized for small magnesium parts: Perfect for lightweight, high-strength components.

By eliminating much of the secondary machining required in traditional magnesium die casting, the A3 MAG SIS reduces both production time and cost, making it an exceptional solution for industries such as aerospace, automotive, and consumer electronics.
