It means the flow path is more than 300 times comparing it`s thickness. So the manufacturing process requires a high injection speed. We will need a optimized Plastic Bucket Moulding Machine to produce the 20 Liter Plastic Paint Buckets. 20L plastic paint kettle is most made with only one cavity with a 650 Ton dedicated injection molding machine. This plastic paint kettle molding machine should have a high injection speed of about 500-600 mm/s, the open stroke should be bigger than 750mm, with a precise mold open controlling system if you may run an in-mold-labeling system in the future.

Frankly speaking, L/D ratio is a very important parameter to a plastic injeciton molding machine. As it affect a lot on the injection machine`s melting performence and final plastic injection molding products quality. As an professional plastic molding machines manufacturer, we would like to explain it more to help our customers to under plastic injeciton molding machines screw better. What is L/D Ratio in Injection Moulding Machine Length-to-diameter ratio or L/D ratio in injection molding machine is the nominal length of the screw divided by the nominal diameter in consistent units. Or we can simply say the L/D ratio is the flighted length of the screw

The minimum and maximum daylight in injection molding machine determines the sizes of the items it can make. The maximum daylight has to accommodate height of moving half of mould, height of moulded part, minimum and enough clearance for removal of moulded part and height of fixed half of mould. Formula to calculate the day light of the toggle injection molding machines: Maximum daylight = Maximum mould height + mould open stroke. Minimum daylight = Minimum mould height + mould open stroke. With Hydraulic clamp machine, Maximum daylight = Minimum mould height + mould open stroke. If shut mould height is more
Read more →Most people in plastic moulding industry may have the same question: how to calculate injection moulding machine tonnage or how to calculate clamping force in injection molding? This is a very common question if you are in the plastic inejection molding industry. So how do you calculate injection molding tonnage? Before answering the question about clamping force calculation, we should make it clear for some basic definition of the injection machine`s molding tonnage and how it comes from and what it supports during the injection molding process. What is tonnage in injection Moulding machine? The “tonnage” is the maximum of clamping force that a injection molding machine can offer to keep the the injection tool tightly closed during the injection process. This clamping force ensure the mold won`t
