Sino Mould company is a leading paintbucket mould maker in China, we make tens sets of paintbucket moulds annually with fine molding solution service. Our bucketmould size range from 1L to 35L, such as 1L, 2L, 3L, 1gallon, 5L, 6L, 8L, 10L,12L, 15L, 16L, 18L, 20L, 25L and so on. We could make the paint bucket mouldwith multi-cavity solution.

For the painting bucket mould, we use P20, 718H, H13 with Cu-Be inserts forbetter cooling. We could design the mould demolding by mechnical ejectionsystem, which is suitable for automatic falling or collect by robot. Usuallythe customer required in mold labeling for the bucket and lid, we could makethe product design change in order to satisfy this requirement, we could makecertain fixing design for heat transfer printing in the bottom of the bucket,so it is OK for both IML molding or after printing.

There have different ways to test the paint bucket sample according todifferent requirement:
1. stacking: bucket by bucket space saving; whole set by whole set balance andstrength inspection.
2. drop testing: when the lid closed with the bucket, we drop the bucket fromthe height 1m(-1.5m), the lid could not be divided from bucket and caused waterleakage.
3. shaking testing: use certain device to test the bucket and lid seal quality.
4. concentricity: Inspect the wall thickness of the bucket.
5. Weight according to tolerance requirement.

As a group company, we could supply whole paint bucket molding service,include paint bucket mould, injection molding machine, necessary additionalmachines and technology support. Welcome to contact us for more information.Thanks.

Dakumar, specialized at offering turnkey solution for plastic production line,  is experienced  with all kind of PET preform production line, such as water preform moulds and machine, CSD preform production line,PET Jar preform production line

PET jar preform production line

Unlike normal preform of water bottle preform or oil bottle preform, PET Jar preform usually have big neck such as 110mm or 100mm, which means that it cannot make many cavity like normal preform. For normal preform, the maximum is 144cavity. But for PET jar preform, usually maximum is like around 8cavity or 12cavity or 16cavity depending on the PET jar preformsize.

Taking 110mm preform mould for example.

For 2cavity mould, DKM180T injection machine is required.( but the injection machine should have enlarged mould thickness).

For 4cavity mould, DKM250T injection machine is suggested.

For 6cavity mould, DKM350T injection machine is suggested.

For 8cavity mould, DKM450T PET injection machine is suggested.

The cycle time is around 25s, will be different according to different preform weight.

For PET Jar preform moulds, we usually adopt shut off valve gate system for the hot runner system, which is controlled by pneumatic device. With this kind of gate, there will be no tail on the preform to avoid cutting the preform moulds manually.

For one PET jar preform mould, DAKUMAR could offer PET Jar preform mould, PET injection machine, auxiliary equipment like loader, dryer, and chiller...And we also supply blowing mould and machine to make PET jar preform to bottle. Apart all from these, SINO could help the customer to start from zero. We could give your suggestion on factory orware house layout, crate trial design.. and when you receive the equipment, we could also send engineer to help you for machine installation and commissioning. And to help you run the PET jar preform production line smoothly in future, our engineer will also give some basic training of your engineer to make surethey will capable of operating the machine.

For more details about PET Jar preform production line, welcome to contact us!
