How To Make IML Bucker Mold

Making an IML (In-mold Labeling) bucket mold is a complex and precise project, which combines traditional injection mold technology with the IML automation system. Next, I will provide you with a detailed breakdown of the production process, key technologies and precautions.

Mould name:Plastic Bucket Mould


Product size:10L/20L


Number of cavities:1 cavity


Die steel material:P20/718H//NAK80/S136H


Mould size:650*650*800mm


Suitable for injection moulding machine:650T


Hot runner:YUDO/HASCO/Master


Ejection system:Push plate ejection


Mould cycle time:35S


Mould life:One million


Mould life :45-65 days

First of all, it is necessary to understand the fundamental difference between IML bucket molds and ordinary injection molds:

Ordinary injection molds: Only produce one plastic bucket body.

IML injection mold: During the injection molding process, the pre-printed label is placed inside the mold, allowing the plastic melt to bond with the back of the label (the printed surface), ultimately resulting in a complete product with exquisite decoration that does not require secondary spraying or labeling.

Therefore, IML molds are not merely molds themselves; they are systems that integrate mechanical, electronic, visual and plastic molding technologies.

Material Selection:

 The material of the bucket is usually HDPE or PP, and the label material is usually PP or PET film. Its shrinkage rate must match that of the plastic of the bucket body; otherwise, it will wrinkle

IML bucket molds are generally produced using 450 to 650T injection molding machines. When using injection molding machines with smaller tonnage for production, there will be a problem of insufficient mold opening stroke.

The main difficulty of the IML bucker mold lies in how to use electrostatic film. The methods of applying the film and taking the item are divided into top pick and side pick. 

The customer needs to apply static electricity to the surface of the label through an electrostatic generator to make it adhere to the surface of the bucket. The mechanical hand must be perfectly synchronized with the injection molding machine cycle, with rapid and precise movements and high repeat positioning accuracy (usually within ±0.1mm).
