Abstract
The plastic product manufacturing industry has been growing rapidly in recent years. One of the
most popular processes for making plastic parts is injection moulding. The design of injection
mould is critically important to product quality and efficient product processing. 4019
Mould-making companies, who wish to maintain the competitive edge, desire to shorten both
design and manufacturing leading times of the by applying a systematic mould design process.
The mould industry is an important support industry during the product development process,
serving as an important link between the product designer and manufacturer. Product
development has changed from the traditional serial process of design, followed by manufacture,
to a more organized concurrent process where design and manufacture are considered at a very
early stage of design. The concept of concurrent engineering (CE) is no longer new and yet it is
still applicable and relevant in today’s manufacturing environment. Team working spirit,
management involvement, total design process and integration of IT tools are still the essence of
CE. The application of The CE process to the design of an injection process involves the
simultaneous consideration of plastic part design, mould design and injection moulding machine
selection, production scheduling and cost as early as possible in the design stage.
This paper presents the basic structure of an injection mould design. The basis of this system
arises from an analysis of the injection mould design process for mould design companies. This
injection mould design system covers both the mould design process and mould knowledge
management. Finally the principle of concurrent engineering process is outlined and then its
principle is applied to the design of a plastic injection mould.

Injection moulds are always expensive to make, unfortunately without a mould it can not be
possible ho have a moulded product. Every mould maker has his/her own approach to design a
mould and there are many different ways of designing and building a mould. Surely one of the
most critical parameters to be considered in the design stage of the mould is the number of cavities,
methods of injection, types of runners, methods of gating, methods of ejection, capacity and
features of the injection moulding machines. Mould cost, mould quality and cost of
mouldproduct are inseparable
In today’s completive environment, computer aided mould filling simulation packages can
accurately predict the fill patterns of any part. This allows for quick simulations of gate
placements and helps finding the optimal location. Engineers can perform moulding trials on the
computer before the part design is completed. Process engineers can systematically predict a
design and process window, and can obtain information about the cumulative effect of the process
variables that influence part performance, cost, and appearance.
2. Injection Moulding
Injection moulding is one of the most effective ways to bring out the best in plastics. It is
universally used to make complex, finished parts, often in a single step, economically, precisely
and with little waste. Mass production of plastic parts mostly utilizes moulds. The
manufacturing process and involving moulds must be designed after passing through the
appearance evaluation and the structure optimization of the product design. Designers face a huge
number of options when they create injection-moulded components. Concurrent engineering
