В съвременното производство на металообработване и прецизност, леене под налягане is one of the most widely used processes for producing complex, high-volume metal parts with excellent dimensional accuracy. Among the various die casting methods, multi-slide die casting и conventional die casting stand out as two distinct techniques, each with its own advantages and ideal applications. This article explores these two processes in detail—explaining how they work, comparing their strengths and limitations, and offering guidance on choosing the right method for your project.
Multi-Slide Die Casting: Precision for Complex Parts
Multi-slide die casting is an advanced form of high-pressure die casting that uses four or more slides—moving sections of the mold that come together perpendicularly to form the cavity. This allows for the creation of extremely detailed and intricate parts with tight tolerances and fine surface finishes.
Ключови характеристики:
Употреби four or more perpendicular slides.
Enables tooling complexity and access from multiple angles.
Designed for производство в голям обем of small, сложни части.
Приложения:
- Електрически конектори
- Automotive sensors
- Компоненти на медицински изделия
- Watch parts
- Lock mechanisms
Предимства:
High precision and repeatability: Capable of holding tolerances as tight as ±0.01 mm.
Faster cycle times: Simultaneous slide movement reduces production time.
Superior surface finish: Reduces or eliminates the need for secondary machining.
Thin-walled parts: Ideal for lightweight, compact designs.
Conventional Die Casting: The Standard for Large Components
Conventional die casting, often referred to as леене под високо налягане (HPDC), is a well-established manufacturing process that uses a two-part mold system. These molds—comprising a stationary half and a moving half—form a cavity into which molten metal is injected under high pressure.
Ключови характеристики:
Употреби two-part tooling (stationary and movable dies).
Suitable for producing larger parts with moderate complexity.
Compatible with a wide range of alloys (алуминий, магнезий, цинк, и т.н.).
Приложения:
- Engine blocks and cylinder heads
- Gearbox housings
- Pump bodies
- Appliance frames
- Lighting enclosures
Предимства:
Efficient for large castings: Can handle bulkier geometries and thicker walls.
Lower tooling costs than multi-slide for simpler shapes.
Високоскоростно производство for medium to large parts.
Multi-Slide vs Conventional Die Casting: A Side-by-Side Comparison
| Особеност | Multi-Slide Die Casting | Conventional Die Casting |
| Mold Configuration | Four or more slides | Two-part mold system |
| Размер на частта | Малки до средни части | Medium to large parts |
| Detail Level | Extremely intricate features | Moderate detail |
| Толерантност | ±0.01 mm or better | ±0.05 mm typical |
| Време за цикъл | Shorter due to multi-slide ejection | Longer due to two-slide operation |
| цена | Higher due to tooling complexity | Lower for simpler parts |
| Обем на производство | Ideal for high-volume small parts | Suited for high-volume large parts |
| Животът на инструмента | Дълги, depending on part complexity | Дълги, but varies with alloy and thermal load |
| Повърхностно покритие | Отлично, Необходима е минимална след обработка | добре, may require machining or polishing |
Choosing the Right Die Casting Method
When selecting between multi-slide and conventional die casting, consider the размер, сложност, and precision requirements на вашите части:
Изберете multi-slide die casting if:
Your parts are small and complex.
You need tight tolerances and fine details.
Surface finish is critical, and secondary operations should be minimized.
Speed and automation are priorities in mass production.
Изберете conventional die casting if:
Your components are larger and less intricate.
You’re working with aluminum or magnesium alloys.
Budget constraints favor simpler tooling.
Your project requires robust parts over detailed features.

1: What is the main difference between multi-slide and conventional die casting?
The primary difference lies in the mold design and tooling. Multi-slide die casting uses four or more sliding tools that move perpendicularly to form complex cavities, allowing for more detailed parts. Conventional die casting uses a two-part mold, making it more suitable for по -голям, less intricate components.
2: Which die casting method is better for high-precision small parts?
Multi-slide die casting is the preferred method for high-precision small parts. Той осигурява тесни допустими отклонения, превъзходни повърхностни завършвания, и shorter cycle times, making it ideal for components like electrical connectors, сензори, and small mechanical assemblies.
3: Is multi-slide die casting more expensive than conventional die casting?
да, на initial tooling cost for multi-slide die casting is typically higher due to the complexity of the mold and slide mechanisms. въпреки това, it often provides cost savings in high-volume production because of faster cycle times and reduced need for secondary operations.
4: Can conventional die casting be used for small parts?
While conventional die casting can be used for small parts, it is less efficient and may not achieve the same level of detail or tolerance as multi-slide casting. For best results in small-part production, multi-slide die casting is generally more suitable.
5: How do I choose between the two methods for my project?
Your choice should be based on factors like размер на частта, geometrical complexity, tolerance requirements, и бюджет.
За малък, сложен, and high-precision parts, choose multi-slide die casting.
За по -голям, по -прости части, especially when cost is a concern, conventional die casting is often the better option.
