IML Container Production Line

Dakumar is the professional Chinese in mold labeling supplier. IML refers to in mold labeling. This molding technique is becoming more and more popular. Because in mold labeling technique can keep the pattern on the product all the time. We can get ready product with pattern after coming out from the mold. Our company is experienced in manufacturing IML container production line with good quality and professional after sales service.


Our branch company Sino Mould is specialized in manufacturing plastic thin wall molds. The steel used for the thin wall container is usually stainless steel like DIN1.2316 or S136 stainless steel. With twice heat treatment to the steel, the hardness of the steel can reach to HRC56. AS thin wall molds need to be produced under high pressure and high speed situation. The steel has to be with very good hardness. Otherwise the mold will be easy wear out and the product will come out with flash easily. The thickness much smaller, the much more difficult the mold is. As mold cavity will be vacuum, plastic flowing is very hard to reach each corner of cavity. So this mold must work upon high speed injection machine. We Dakumar machinery spent big efforts in developing high speed injection machine which can provide the demands for thin wall molds.


We developed four size high speed injection machines which can realized the demands for most of the thin wall molds. They are:


-DKM-200H/HH  


-DKM-300H/HH


-DKM-400H/HH


-DKM-600H/HH


The components of the machine are all with very good brand. It can basically ensure the quality of the machine. This high speed injection machine with the advantage of high speed; high efficiency; high safety; high precision; high energy saving. Machine adopts high precision single cylinder injection system especially suitable for high speed injection, with low-inertia and high response speed. Accumulator to realize high speed injection, the max injection speed can reach 300-400mm/sec. Machine ACC/DEC response time can reach 30ms.

IML System

(I-M-L) process refers to in mould labeling system, it is an ideal alternative to elaborate secondary operations such as subsequent printing, and the application spectrum for it reaches from technical articles to packaging products for food. I-M-L technical is a pre-decorating technique, a label to be put in plastic product before plastic product being filled forming. With I-M-L technique, the label and plastic product is one piece product, Label cannot be taken away from the plastic product.


I-M-L system required equipments:


a.Injection system:

· plastic injection molding machine

· plastic raw material dryer

· plastic raw material auto loader

· plastic injection mould

· air compressor

· water chiller


b.Robot system:

· label collecting

· Gripper for feed the label into the mould.

· Sucker for picking out the plastic labeled parts.

· Stacking unit for stacking the plastic labeled part.

· conveyor


C.Labels:

Label color: All kinds of coloraccording to customer’s requirement 

Label size: According to plastic parts and customer’s requirement

Label material: PP, YUPO, PET and so on


There are different types of I-M-L system:


· Side entry robot from Italy+servo motor and High speed injection machine+air compressor + water chiller+plastic injection mould, the whole I-M-L system running cycle time is 4-5 seconds.


· Side entry robot from Italy + High speed injection machine+air compressor+ water chiller+plastic injection mould, the whole I-M-L system running cycle time is 5-6 seconds.


· Top entry robot from Italy+ High speed injection machine+air compressor+ water chiller+plastic injection mould, the whole I-M-L system running cycle time is 7-8 seconds.


· Side entry robot from China+ High speed injection machine+air compressor+ water chiller+plastic injection mould, the whole I-M-L system running cycle time is 7-8 seconds.


· Top entry robot from Italy+ High speed injection machine+air compressor+ water chiller+plastic injection mould, the whole I-M-L system running cycle time is 10-11 seconds.


How is I-M-L system running?

The gripper pick up the label from label magazine,and put label into mould cavity,then the mould close and injection,then mould open,sucker pick out the plastic labeled part,then stacking unit will stack the plastic labeled parts onto conveyor. finally, the beautiful plastic product is shaped.


The advantages of the In Mould Labeling process:


IML, in comparison with the conventional decorating methods,offers a number of benefits:


· IML impresses by the outstanding quality of the decoration with a high brilliance which is achieved by either offset or gravure printing.


· Printing on the container base (e.g. EAN code for convenient scanning) becomes ever more important. The IML process permits to decorate all five outside surfaces of the container in one single operation.


· The IML method can enhance the barrier properties if multilayer labels are applied to the entire outer surface of the container, and even extend the durability of the contents.


· The label inserted by the IML process gives the mould a higher stiffness.


· IML enables the production of decorated and packed containers in a single working step. Internal transport and intermediate storage are thus eliminated.


· IML permits to change the container decoration (label) without interrupting production.

What is In Mold Labeling (IML)?


In-mold labeling is a pre-decorating technique used worldwide for blowmolded bottles as well as injection molded and thermoformed containers or other plastic objects. Pre-decoration is the application of a label to a container before it is filled with product.


Labels for injection molded IML do not require an adhesive on the back side. The IML process eliminates the labeling step and all associated equipment and labor.


In the in mold labeling process, a label or applique is placed in the open mold and held in the desired position by vacuum ports, electrostatic attraction or other appropriate means. The mold closes and molten plastic resin is extruded or injected into the mold where it conforms to the shape of the object.


Why is in mold labeling is so popular?

Because In mold labeled containers offer these advantages:

-Lower costs than other pre-decorating methods.


-No extra labeling step or equipment.


-In-case product filling and capping.


-Increased packaging line speeds.


-Reduces in-house container inventory.


-Reduced container weight.


-Improved appearance.


-Better stain resistance.


-Improved sidewall strength.


-Better squeeze resistance.
