Your Complete Guide to In-Mould Labelling

In-mould labelling (IML) machine is used for the process of decorating or labelling plastic products during the manufacturing process. It involves placing a pre-printed label or graphic image into a mould, and then injecting molten plastic into the mould, fusing the label and plastic together to create a seamless and durable final product.

In-mould Labelling or Decorating Machines are a popular choice for manufacturers looking to create attractive, functional, and long-lasting plastic products that can stand up to a variety of harsh environments and conditions.

Different Types of In-mould Labelling

There are three methods of in-mould labelling printing process viz. Blow moulding, injection moulding, and thermoforming.

These methods use different types of labelling or decorating machines. These methods are –

1.    Blow Moulding

Blow moulding is a manufacturing process that creates hollow plastic parts, such as bottles, containers, and other similar items. The process involves melting plastic resin into a molten state, then extruding it into a hollow tube, called a parison. The parison is then clamped into a mould, and air is blown into it, causing it to expand and conform to the shape of the mould. After the cooling and solidification of the plastic, the mould is opened, and the finished product is removed.

There are several types of blow moulding, including extrusion blow moulding, injection blow moulding, and stretch blow moulding. Each of these methods has its specific advantages and applications, but all are based on the same basic principles of melting, extruding, and shaping plastic.

Blow moulding is commonly used to create plastic bottles, containers, and other similar products, and is valued for its efficiency, speed, and ability to produce large volumes of identical parts. Plastic processing machinery in Australia is widely used in the packaging industry for a variety of consumer products, including food and beverage containers, cosmetics, and household products.

2.    Injection Moulding

The injection moulding manufacturing process is used to produce a wide variety of plastic products. The process involves melting plastic pellets or granules and then injecting the molten plastic into a mould under high pressure. Once the plastic cools and solidifies in the mould, it is ejected, and the process can be repeated.

The injection moulding process begins with the creation of a mould, which is typically made of metal and designed to match the shape and dimensions of the final product. The mould is then clamped shut, and the plastic pellets are melted and injected into the mould at high pressure. The plastic quickly fills the mould, taking on its shape and texture. The mould is then cooled to allow the plastic to solidify, and the finished product is ejected.

Injection moulding is a highly efficient and cost-effective manufacturing process, capable of producing large quantities of identical parts with high precision and accuracy. Plastic processing machinery in Australia is widely used in the production of a variety of plastic products, including automotive parts, medical devices, toys, household appliances, and many other consumer and industrial goods. Their versatility and reliability make them a popular choice for manufacturers across a wide range of industries.

3.    Thermoforming

Thermoforming manufacturing process creates plastic products by heating a sheet of thermoplastic material, such as acrylic, polycarbonate, or PVC, until it becomes soft and pliable, and then shaping it into a specific form or shape using a mould. The process is known as "thermoforming" because it involves the use of heat to mould and form the plastic material.

The thermoforming process typically involves the following steps: first, a sheet of thermoplastic material is heated to its softening point using an oven, infrared heaters, or other heating methods. Next, the softened plastic sheet is placed over a mould, which can be made of wood, aluminium, or other materials, and then a vacuum is used to draw the plastic sheet onto the mould, conforming it to the shape of the mould. Once the plastic has cooled and hardened, it is removed from the mould, and any excess material is trimmed off to create the final product.

Thermoforming is used to produce a wide variety of products, including packaging materials, plastic trays, display stands, signs, automotive parts, and many other consumer and industrial goods. It is a cost-effective and efficient manufacturing process that is well-suited to producing large quantities of identical parts with consistent quality and precision.

Advantages of In-mould Labelling

In-mould labelling or decorating machines are commonly used in the production of plastic containers, such as food containers, paint buckets, and other types of packaging. The advantages of IML include high-quality, high-resolution printing, durability, and resistance to fading, scratching, and moisture. In addition the label is integrated with the plastic during the moulding process using plastic process machinery in Australia. It cannot be removed or misplaced, ensuring that the product remains properly labelled and branded.

In-mould labelling (IML) offers several advantages compared to traditional labelling methods, including:

1. Durable and long-lasting: IML labels are fused with plastic during the moulding process, which makes them more durable and resistant to wear and tear. The label cannot be removed or fall off the product, ensuring that the branding and labelling remain intact throughout the product's lifespan.
2. High-quality printing: IML labels use high-resolution printing, which allows for more detailed and intricate designs, logos, and text. This results in a more attractive and visually appealing product.
3. Greater design flexibility: IML allows for more design flexibility since the label can be seamlessly integrated into the product's shape and design, resulting in a more aesthetically pleasing product.
4. Cost-effective: IML is a cost-effective labelling method because it eliminates the need for a separate labelling process, which saves time and labour costs. Additionally, IML reduces the amount of scrap material generated during the manufacturing process, reducing waste and lowering costs.
5. Environment-friendly: IML is an eco-friendly labelling method because it reduces waste and eliminates the need for secondary packaging, which results in a smaller carbon footprint and lower overall environmental impact.
