[Technical Introduction] Hot stamping process that adds a sense of luxury to plastic products.
It contributes to product differentiation! Hot stamping (foil stamping) that gives plastic products a sense of luxury with a metallic shine.
Hot stamping, also known as "foil stamping," is a printing technique. By applying heat and pressure with a special relief plate to a foil film, patterns and designs can be transferred onto products. This technique can impart a sparkling shine and special texture, contributing to the creation of a luxurious feel for products, differentiation from other products, and enhancement of brand image. **Advantages of Hot Stamping Processing** - **Luxury Feel:** It can add a luxurious feel to products with a metallic luster! - **Streamlined Process:** It eliminates the need for processes such as masking and drying required for painting or plating! - **Low Environmental Impact:** Unlike painting or plating, it does not require chemicals, solvents, or solutions, thus reducing environmental impact. - **Compact:** It does not require large equipment! Hot stamping machines can be small enough to fit on a tabletop. Compared to painting or plating, it can be introduced in a space-saving manner. - **Diverse Variations:** With a rich variety of foils, it is possible to achieve various expressions beyond metallic textures, such as wood grain, leather, and scales! - **Small Lot and Variety Support:** By changing the foil or plate, it is easy to accommodate small lots and a variety of products!
basic information
**[Mechanism of Hot Stamping Processing]** Hot stamping processing requires: ▶ Hot stamping machine ▶ Foil film ▶ Hot stamping plate (plus jig) The mechanism involves applying pressure and heat to the foil with the plate to transfer the foil onto the molded product. **[Hot Stamping Plates for Plastic Molded Products]** There are two main types of plates used for hot stamping processing on plastic molded products: - Rubber plates - Metal engraved plates In many cases, a rubber plate made by attaching a special heat-resistant rubber to a metal such as aluminum is used.

Applications/Examples of results
Hot stamping processing is commonly adopted for resin products and plastic molded items, with applications in automotive parts, cosmetic containers, and home appliances being notable examples. ▶ Automotive Parts Hot stamping is frequently used for both interior and exterior components. It is not limited to obvious places like emblems; by applying hot stamping to details such as levers, meter rings, and pointer indicators (the needle of the meter), a sense of luxury and design that cannot be achieved with plastic molded products alone can be imparted. ▶ Cosmetic Containers Hot stamping is widely used in various places, from the outer paper packaging to the inner plastic bottles and tube containers. ▶ Others (Home Appliances, Fishing Gear, Pharmaceuticals, Amusement Related) Home Appliances: In addition to company logos and product names, button areas may also be processed with hot stamping. Fishing Gear: Lures that sparkle and attract fish are often processed with hot stamping! There are even foils specifically for lures. Amusement Related: Hot stamping is frequently used in parts of pachinko machines and toys.
Detailed information
-
In hot stamping processing of plastic molded products, a rubber plate with a special heat-resistant rubber adhered to metals like aluminum is often used. Unlike paper products, plastic molded items have sink marks (indentations that occur during injection molding) and distortions, resulting in an uneven transfer surface. The rubber plate has higher cushioning properties compared to metal plates, which allows it to absorb these indentations and distortions, ensuring better adhesion to the transfer object (workpiece) and resulting in fewer decoration defects, as well as being less likely to damage the transfer object.
-
Metal sculptures made of materials like iron and brass have characteristics such as higher reproducibility of designs compared to rubber plates, allowing for expressions that resemble being pressed into printed materials.
-
Up-and-down method A method of hot stamping where a hot stamp plate is pressed against the printed material to transfer foil using heat. It can accommodate printing not only on flat surfaces but also on curved surfaces.
-
Roll-on method This method is used when applying hot stamping to the outer circumference of cylindrical products. The product is set in a machine and rotated while being pressed against the plate, allowing the foil to be heat-transferred onto the printed material.
