The Marvellous World of Manufacturing

Not many people give much thought to the fact that almost every object you touch as you go about your day had to be manufactured by someone. When you stop to consider the impact that the processing and manufacturing industry has had on the modern world, it can blow your mind. My mind was blown when my son arrived home from his new job at a local processing and manufacturing plant and told me about the industry he was now working in. Since then, I have learnt all kinds of cool things which I would love to be able to share with the rest of the world.

Selecting the best die casting process

by Anthony Harvey

Die casting refers to the process of creating metal parts by pouring molten metal into a mould cavity. The result of die casting is that the metal formed will be smooth with definite dimensions. It is a common process for metals such as aluminium, steel, lead, copper and iron. Notably, because different metals have different properties, for optimum cost-efficient and time-sensitive die casting; you will need to use a method that is compatible with the circumstances.

There are two die casting methods: hot-chamber die casting and cold-chamber die casting. For a good outcome, you will have to ensure that the properties of the metal are compatible with the capabilities of the process used. While the method will always depend on the type of metal, there are several other factors that ought to be considered. This article will look into a little of detail when it comes to selecting the ideal casting process.

The size and weight of the part to be die casted

You will notice that each casting process has a unique weight that it can support under normal circumstances. The weight is usually a range, and it is advised that you do not exceed the maximum weight or die cast parts whose weight fall below the minimum allowed weight. Usually, the process should work even if the weight is exceeded, except that the best results are yielded when die casting is done to parts that fall within the relevant range. The same applies when it comes to size whereby you are expected to limit yourself to the recommended size for quality results.

The time available

When considering the time, do not focus on the amount of time it will take for the process to be complete once initiated, but also look at the time it takes to assemble the tools for either process. The amount of time required to assemble tools is sometimes referred to as lead time and is about 12-16 weeks for die casting. Technically, cold chamber die casting takes a lot of time compared to hot chamber although it is cheaper in the end. As such, if you want a fast process, consider hot-chamber die casting. It also important to look at the number of units that the process can yield per hour, although die casting generally yields more than 1000 units per hour.

The cost

Purchasing and preparing die casting equipment is costly, and while using, you want to minimize the amount of money you spend after you have acquired all the equipment and tools. Look for the best die casting process that will minimize things such as labour costs.
