CHOOSING THE CORRECT MOULDING SYSTEM

A crucial STEP for any start up. The process must starts with the product to be
manufactured.
Note down the weight, dimensions, thickness, material of make of product.
Determine the expected production required per month / day. Based on company
working hours back calculate the pieces required to be produced per minute.
From this, assuming 3-4 cycles per minute, No. of cavities required in mould to
achieve expected production is ascertained.
The number of mould cavity will provide for the total shot weight per cycle (No of
cavities x weight of product + runner)
Hence with above information one can choose the machine with appropriate shot
weight. Other consideration includes the tonnage required to compensate for the
filling pressures, which depends on the part thickness and product design - length,
undercuts and other features.
Choosing wisely and scientifically from wide range of options available for shot
weight, tonnage , level of automatons and energy savings one can be assured of
quality production economically in ones budget.
A few considerations when selecting the system to use include:
• Part complexity
• Color requirements & Color changes during production run
• Physical characteristics of material
• Type of plastic material to use - virgin or "regrind”
• Single or multiple design production
• Volume of parts to be produced
• Production speed required
Each molding system offers advantages and disadvantages. We can help you
select the correct molding system to manufacture your plastic parts economically
