Cost-effective Strategies of Mold Making

Plastic Mold manufacturers of any type of mold need to optimize the process of costing. This helps moldmakers significantly to improve product quote accuracy and fasten Request for Quote (RFQ) response as well. It’s a no less than a challenge for moldmakers to come up with cost effective methodology of production. To achieve accuracy in product cost quotes is difficult, but possible.

The challenge for offering savings and efficiencies requires moldmakers to include the need for:-

  1. Reduced overhead costs – Turning around a detailed, inaccurate quote can be time consuming and expensive as well.
  2. Increased precision – Many mold manufactures fail to understand the costing process of molds. Understanding the costing process is not an easy task. Mould manufacturers have to focus on the moldmaking procedure. To be aware of every nook and cranny of the mold-making process adopted is essential to gauge its effectiveness. Existing quote is liable to have discrepancies with actual costs, if you lack the know-how of the moldmaking process. It is very important to have a clear knowledge of the actual costs of molds. Such understanding is necessary for winning fresh, profitable business.
  3. Faster response times – The capacity to shift quotes is a notable competitive edge for many moldmakers. However, for shifting quotes, a moldmaker has to have a lot of cutting-edge tools and technologies.

Plastic Injection Molding in a Nutshell

There are many conspicuous examples of moulds in our daily life. Have you ever wondered that how various objects around us acquire their shape? The answer to this is injection Molding (IM). The idea was conceived in 1930s and gained popularity when manufacturing plastic commodities led to greater scrap wastes and extended production time while devising alternative manufacturing technique.

Difference between injection molding and conventional metal die casting

The basic difference between injection molding molds and metal die casting is that the latter requires molten material (metal) to be poured in the casting; however, the former needs the melted plastic residuals to be injected forcefully into the mold.

 What kind of plastic is suitable for molding machines?

 The notion of using ‘any kind’ of plastic for getting the desired shape is gravely wrong. Thermostat plastics such as nylon, polystyrene, polythene and polypropylene are ideal for IM technique. Continue reading

Nitty-Gritty of Water Assisted Injection Molding

The advent of evolving injection moulding technologies has effaced the older techniques of the process. One such advanced technique is Water-assisted Injection Moulding (WAIM). The technique is developed to manufacture products with intricate geometric shapes. It is advisable to use WAIM technique with a hot runner mold to shape the products in the desired form for effective results.

Water-Assisted Injection Molding- An Introduction

Water-assist Injection Moulding (WIAM) is a cutting-edge development in the realm of injection moulding (assisted). Similar to a gas-assisted injection moulding process, WIAM uses high-pressure water fluid to shape a plastic part present in a mould. The primary benefits WIAM over other techniques are:-

  • Cheap tool cost
  • Less material cost
  • Splendid part consolidation

Nevertheless, the differences between gas and water help WIAM technique to have multiple common advantages such as:-

  • The technique can produce 20% thinner wall sections
  • The cooling cycle time is 50% faster

Some knowledgeable technologists combine both water- and gas-assist techniques to enjoy the best of both the worlds. Also, every leading Pet Moulds Manufacturer in India is churning out moulds that are specifically meant for the Water-assisted Injection Moulding. Continue reading
