Case Studies
Our exceptional ability to solve even the most complex manufacturing riddles is what makes us loved by customers all across the globe. We excel in die casting, engineering, HPDC expert assistance, machining and prototyping. Our case studies offer you a quick view into our team's incredible ability to offer superior quality products.
The die designer is constrained by the part design as it is an end-user requirement, over which he has very limited or no flexibility. Generally, the design of an HPDC die starts with part modeling, followed by the shot design.
Automobile alternator is an assembly of Slip Ring End (SRE) Bracket and a Drive End (DE) Bracket as the casing and the other parts are housed inside them. This customer was complaining of the binding.
The first case study was one of the earliest applications for the author in terms of simulation. One of the customers came with a RFQ for a group of parts for a compete assembly, mostly with HPDC except one part.
FAQ
What do you mean by high pressure die casting?
It is a comparatively complex process carried out by using a securely locked die cavity. Using high pressure and velocity, molten metal will be injected into this cavity. The application of high pressure ensures the quick release of gas within the mould. High velocity ensure quick and easy filling and results in sound castings.
How does the process of high pressure die casting work?
High pressure die casting is the quickest way to convert a molten metal to a completed component. Molten metal can be injected into a hard steel mould and allowed to solidify under pressure before it is ejected.
For what purpose high pressure die casting is used?
Generally, in case you need larger volumes of complex components, you can go for high-pressure die casting. It will deliver the components with high precision and speed. Compared to other methods, the casting cycle for high-pressure die casting is very concise. The molten metal will be solidified in mere seconds. Also, high-pressure die casting creates smooth surfaces. This will act as a great primer for the next stage of coating applications.
Does CRP India offer prototyping services?
Yes. We can offer the most reliable and efficient prototyping services. Our design and sales engineers are well-experienced in handling the prototypes for automotive, aerospace, defence, medical, and consumer electronics industries, to name a few. Whatever the precision metal component you require, we help you optimise the prototyping process for it.
Can you explain the difference between low pressure and high pressure die casting?
Low pressure die-casting is slower when compared to the components produced using the high-pressure die-casting process. The size of casting may also be limited due to the machine size in low-pressure die casting. High-pressure die casting offers varied sizes, and it can be easily carried out on soft alloys like aluminium and zinc.
Does CRP India have its own machine shop, tool room and casting shop?
Yes! We manufacture the dies/tools in our tool room as per customer requirements. We have machine shops and die casting as well.
Why is die-casting comparatively an expensive process?
Die casting can be expensive because the initial die casting tooling outlay will be costly. Hence, the unit cost savings won't be justified until you reach a reasonable volume. But the tooling manufacturing process is evolving, and the break-even threshold is also coming down. Hence, the costs may also be reduced in the near future. You should consider the precision, minimum post-molding operations, close to final shape finish achieved through Diecasting process, resulting in much reduced cost overall. Just send us your RFQs and we will revert no mater the requirements.
What is the maximum size of die casting you can produce?
CRP India mainly specialises in small, precision die casting components. We can cast die casting components up to the size of a computer or laptop. It may vary based on the weight of the component. But, we are specialised in creating components that can easily fit in your palm or even at the tip of your finger. However we shall develop and manufacture larger dies and produce castings with 3rd party and supply any size of the part. Feel free to send us your RFQs and we will revert back swiftly with respect to feasibility including size, material, castability, operations, finish, etc.
Will you be able to customise the components to suit my needs?
Definitely! We can discuss your requirements before the mould design stage itself. We will customise the castings and deliver the components you require.
How is the casting pressure calculated?
The die-casting pressure/ machine clamping force (t) = Casting projected area x modulus (sq.cm) x ( die casting projected area / orthographic die casting projected area) x Yield Factor (say 1.4)
What type of customers do you serve?
We serve global giants with the help of our cutting-edge technologies and customer-centric business methodologies. We serve industries like furniture and luminaries, hydraulics and pneumatics, electrical and electronics, aerospace and defence, and auto components building.
Why do you use Aluminium in die casting?
Aluminium can easily withstand corrosive resistance with suitable surface treatments coupled with mechanical properties, thermal and electric conductivity, makes it a great alloy for die casting.
Light weight and Recyclability makes it a very popular alloy across various industries.
