Plastic oil drum blow mould manufacturer
A drum is sold by its weight. A gram too much is money given away on every one; a gram too little and it splits on the road. Where that weight sits is decided in the mould, not on the machine.

Where the wall of a drum is decided
A drum has to do three things at once: stand three high in a warehouse without slumping, survive being dropped off a tailgate, and weigh what you costed it at. All three are the same question, which is how the wall of the parison is distributed as it goes into the tool. That is designed into the mould and the pinch-off; it cannot be fixed later by turning up a dial on the machine.
The tooling here is extrusion blow, so there is no runner system and nothing to trim off a gate. What we design is the cavity, the cooling and the pinch-off, and what we ask you for first is the drum weight you are aiming at and the machine it has to run on.
Send the capacity you want and the target drum weight, and you get a straight answer for that drum. North American buyers write oil drum blow mold and HDPE drum mold.

Seven questions about the tool itself
The seven that decide whether you order, answered for this tooling. Where a figure is on the drawing we print it; where it depends on your part we say which numbers we will ask you for.
Hot runner or cold runner?
Neither. Extrusion blow tooling has no runner system at all: the parison comes off the die head of the machine, so there is nothing hot or cold to choose. What we design instead is the cooling circuit and the pinch-off, and both are drawn for your drum.
Cycle time and output
On the blow side the cycle belongs to the wall, the cooling and the machine together. Tell us the drums per hour you need and how many cavities your machine carries, and the figure is worked out with you rather than quoted blind.
How the part is ejected
A blown drum is not pushed out by pins. It is released when the halves open and taken away by the machine; what we design is the pinch-off and how the flash comes off. That layout is drawn before any steel is cut.
Tryout report and acceptance
The mould is fitted to a machine here and drums are blown before it ships, and those drums travel in the crate. Drum weight, the capacity to the fill line, the drop test and the stacking test are the usual acceptance points.
Spare parts
Cavity halves, neck inserts and pinch-off inserts are cut from the same drawings. The pinch-off is what wears first on drum tooling; say how many spare sets to pack.
Warranty
Warranty terms are written into the quotation for that tool.
Will it fit your machine?
This is the first question on a drum mould, not the last. Send the make, model, platen size, daylight and die head of your extrusion blow machine. The tool is designed to that machine and the fit is confirmed before cutting.
What we will ask you for: the capacity, the drum weight you are aiming at, the material, whether it needs a handle or a level stripe, the drums per hour, and your blow moulding machine.
What should your drum weigh?
The target weight is the number the whole tool is designed around. Tell us the gram weight you costed the drum at and the wall distribution is worked to it.
