Our high-pressure die casting technology used at TOPS Precision is designed to achieve high levels of dimensional accuracy, high quality of the surface, and consistent mechanical performance, and is used in high-pressure demanding industries, including automotive, electronic, medical, and industrial applications.
TOPS Precision has developed end-to-end solutions to high-pressure die casting, featuring advanced die cast machines, tooling expertise, and quality systems ISO certified, and offers design and advice services, high-pressure die cast moulds, mass production, and post-processing. Our HPDC services are tailored to cost-optimize performance and time-to-market, whether you need high-volume manufacturing or rapid prototyping.
The following are our main features:
Die casting results in a part that has smooth and refined sides the moment it is cast. This reduces the chance of secondary finishing, which is often comprehensive. Assembly components produced by HPDC can be used in industries that require beauty, bonding of their finishes, or surfaces to be covered.
HPDC can have tight tolerances and repeatable accuracy due to the control of the injection parameters and the use of rigid steel molds. This accuracy minimizes the excessive machining and ensures compatibility with complex assemblies.
Die casting under high pressure enables a thin-wall component to be cast without losing strength or integrity. The capability facilitates lightweight construction efforts, particularly in the automotive and electronic sectors.
HPDC is suitable for high-speed production. It is one of the most cost-effective processes of large-volume production due to fast cycle time, automation, and extended (long) life of molds.
High-pressure die casting includes a metal casting technique where molten metal is forced into a steel mold (die) with a very high pressure -usually 1,000 to more than 20,000 psi. The molten metal is filled into the mold cavity at a very high rate, solidified under pressure, and a dense and dimensionally accurate part is formed.
This is applied mostly to non-ferrous metals, which include aluminum, zinc, and magnesium. HPDC is best suited for the impressioning of complex shapes, thin sections, and components with a tight tolerance and surface quality.
At TOPS Precision, our production process is planned and transparent to achieve stable quality and efficiency in production.
The customers provide 2D drawings or 3D CAD models. Our engineers also examine the design in terms of manufacturability, material selection, and wall thickness, draft angles, gating, and tolerance requirements. We give specific Design for Manufacturability (DFM) responses to minimize the cost and performance.
In house tooling department designs and produces high-precision steel molds. Mold design focuses on:
Exactly controlled pressure and temperature are applied to the mold until molten metal flows into the mold. Automated HPDC machines provide low defect rates, uniform filler, and high repeatability of production batches.
Parts can be cast, and then trimmed, deburred, CNC machined, drilled, tapped, or milled. Surface finishing processes are anodizing, powder coating, plating, painting, and polishing.
Each batch of production is subjected to dimensional inspection, visual inspection, and process control. They offer quality documentation and inspection reports to suit the requirements of international customers.
TOPS Precision provides an overall scope of HPDC services that are industry-specific and volume-dependent.
It is best suited for manufacturing lightweight parts with high strength and good Thermal and corrosion resistance. TOPS Precision produces thin-wall, complex-geometry, and stable-mechanical property aluminum HPDC components. They’re mainly used in automotive part applications, electric vehicle housing and heat sinks, and also in industrial enclosure applications. The mechanism provides a high performance, durability, and efficiency ratio.
Zinc high-pressure die casting is ideal where accurate parts must have tight tolerances and excellent finishes. The superior flow properties of zinc alloys enable finer details to be cast in without much after processing. This renders zinc HPDC a cost-effective option in high-volume production of small to medium parts where precision and appearance are of utmost importance.
High-pressure die casting of magnesium allows fabrication of high strength to weight ratio ultimate weight components. TOPS Precision uses controlled processes to obtain stable quality and dimensional consistency, allowing magnesium HPDC to be used in automotive, mobility, and premium electronics applications where weight-saving is vital.
TOPS Precision has its own design of mould and manufacturing of moulds to ensure complete control ofthe quality of tools and manufacturing performance. SA strategyof optimization of the mold design, effective cooling, and correct ventilation will result in stable production, decreased lead times, and less tooling expenses throughout the project lifetime.
So, here are some of the important materials we use in high-pressure die casting:
Material | Common Grades | Key Properties | Typical Applications |
Aluminum Alloys | A380, ADC12, A360 | Lightweight, corrosion-resistant, good thermal conductivity | Automotive housings, heat sinks, industrial enclosures |
Zinc Alloys | Zamak 3, Zamak 5 | Excellent dimensional accuracy, smooth surface finish | Precision components, connectors, consumer products |
Magnesium Alloys | AZ91D, AM60B | Ultra-lightweight, high-strength-to-weight ratio | Automotive parts, aerospace components, electronics |
Top Precision has made sure that it incorporates the best high-pressure die-cast technologies in its operations in order to guarantee a high level of consistency in its performance and quality.
Vacuum-assisted die casting can reduce the amount of air trapped in the mold cavity, which increases porosity and enhances the density and mechanical strength of cast components. The method improves the quality of its surfaces and helps in applications where the structural integrity should be stronger.
Die casting cells enhance production control and predictability through standardization of cycle time and minimization of variability. Robotic handling ensures safety and repetition as well as stability of the entire process and is especially suitable inhigh-volumee production.
High-level mold systems with moving cores allow the creation of complicated geometries and interior elements within one casting cycle. This minimizes the secondary operations, enhances dimensional accuracy, and reduces the total cost of production.
Key parameter processes (pressure, temperature, and fill speed) are monitored in real time to maintain stable production and quality parts. The continuous control of the process makes it possible to early detect the deviations and to ensure the uniformity of mechanical properties between batches.
The following is the difference between low-pressure diecasting and high-pressure diecasting:
Aspect | Low-Pressure Die Casting (LPDC) | |
Metal Filling Method | Molten metal is pushed into the mold using low, controlled pressure | Molten metal is injected into the mold at very high pressure |
Typical Pressure Range | 0.2–1.5 bar | 1,000–30,000 psi |
Mold Type | Permanent steel mold, often gravity-assisted | Hardened steel mold designed for high-speed injection |
Production Speed | Moderate cycle times | Very fast cycle times |
Dimensional Accuracy | Good dimensional accuracy | Excellent dimensional accuracy |
Surface Finish | Smooth, may require minor finishing | Excellent surface finish with minimal post-processing |
Wall Thickness Capability | Medium to thick walls | Thin-wall capability |
Porosity Level | Very low porosity | Higher risk of porosity without vacuum assistance |
Mechanical Properties | Superior strength and integrity due to low turbulence | Good mechanical properties, improved with vacuum HPDC |
Heat Treatment | Suitable for heat treatment | Limited heat treatment due to porosity risk |
Tooling Cost | Moderate tooling cost | Higher tooling investment |
Here are some of the important tips to reduce the HPDC cost:
