This is a small diameter hose for automobiles (the product shown is approximately φ16). Due to its long and curved shape, the suitable molding method for this product is three-dimensional blow molding. Even with blow molding, it is possible to shape thin hose forms. It can fit into restricted storage spaces. Additionally, there are multi-cavity molds that can produce two products from a single mold for smaller products and those with a short overall length. Currently, in home appliances, efforts are being made to reduce weight and improve costs by converting hoses from metal to resin.

• Plastic Mould

The circular opening can be opened and closed with a three-part sliding mechanism. The main feature is that two plate-like injection-molded parts are installed near the bellows. To achieve this structure, all parts behind the bellows are designed to fit within the slide. This product, which uses a component longer than 300mm for product demolding and also incorporates the insert slide, is composed of a two-stage sliding (parent-child) structure. Therefore, at the manufacturer's request, it has been consolidated into a single component made up of seven parts.

• Plastic Mould

The shape is designed to connect two molded products, allowing for two pieces to be produced with a single mold. After molding, the purple section is cut away, resulting in two molded products. Since two molded products can be created in one cycle, it is suitable for mass production. Additionally, it allows for the integration of injection-molded parts, eliminating the need for post-processing welding work. This is a molded product that takes advantage of the characteristics of three-dimensional blow molding.

• Plastic Mould

Since it is a bumper for automobiles, it requires rigidity, hardness, and performance in high-temperature environments. The material is PP+PE-TD10 (a composite material made by adding 10% talc to a blend of polypropylene and polyethylene), which meets the application requirements. Additionally, talc-reinforced polypropylene is suitable for applications that require lightweight materials.

• Plastic Mould

This is a product where the flange part is integrally molded using only a direct blow molding mold. There is no need to separately manufacture the flange (component) by injection molding and then weld it.

• Plastic Mould

Blow-molded products have a hollow interior. Utilizing that characteristic, boats can float on water. There are many blow-molded toy products readily available.

• Plastic Mould

It is a tank for pesticide spraying that is carried on the back. Two injection-molded parts for shoulder straps and two resin nuts are each inserted. Additionally, the part that holds the pesticide and the part that stores the engine are separated by pressing. The underside of the foot part is designed with a sliding structure across the entire back, allowing the resin to extend to the narrow toe, and it is configured to be molded as a single unit with both a plate-like shape and a blow tank shape.

• Plastic Mould

This is a tank for pesticide spraying mounted on a drone. It incorporates four injection-molded parts and eight flange nuts. The pins supporting the four nuts arranged on the vertical wall perpendicular to the parting line are designed to slide, as they would obstruct the release. Additionally, the screw section (purple) has been machined to fit a cap provided without a drawing.

• Plastic Mould

It has a U-shaped curved form. The center of the product is a "crushed shape" formed by crushing resin within a mold. Therefore, it will be direct blow molding instead of three-dimensional blow molding, which is good at creating curves.

• Plastic Mould

We have created molds for medical beds. You have ordered five types of molds to produce the product shown in the image. The product is thin, but it has many uneven surfaces, so it is important to properly place air escapes in the right spots to ensure it expands well.

• Plastic Mould

This is a pop sign that is active in various locations, both indoors and outdoors. The main body is made of polyethylene, and the panel is composed of shatter-resistant polyethylene terephthalate. It features an excellent design for visibility and durability.

• Plastic Mould

This product can insert nine injection-molded parts using direct blow molding. All inserted components are released by a sliding mechanism. Since the mold is fixed in the vertical direction, it is necessary to carefully secure the inserts to prevent them from falling. Additionally, this product has two types with different shapes from the inclined part to the opening, but the mold is divided so that it can accommodate both types with a single mold, allowing for the production of two types of products by partially replacing the components.

• Plastic Mould

Direct blow molded products. In a single molding process, two types of pipe products that combine the functions of an air duct and a resonator are formed. After molding, they are separated at the central purple section. Even if the shapes are different, it is possible to achieve set taking under certain conditions.

• Plastic Mould

This is a product with a shape resembling a cobra's head, featuring rubber-like injection molded parts and small pipe injection molded parts inserted on the sides. Both insert components have a slide structure that includes a core, which also serves to prevent punctures. Additionally, the bellows shape is designed for a release slide specification. The small opening has a slight undercut relative to the mold split, but since the material is soft, it can be released without difficulty. In this case, if the customer agrees, we can propose a solution that does not use a slide structure to reduce mold costs.

• Plastic Mould

The resonator and duct were integrated and molded into a single part using the same mold, resulting in one component. The insert for the injection-molded product is also included. Normally, two types of molds would be required: one for the resonator and one for the duct. Additionally, a process to fit the two types of parts together would be necessary after molding. However, by integrating the resonator and duct into a single mold, we can reduce mold costs and shorten the work process. This specification is made possible by direct blow molding, significantly reducing costs.

• Plastic Mould

Since it is a fender for automobiles, rigidity, hardness, and performance in high-temperature environments are required. The material is PP + PE-TD10 (a composite material made by adding 10% talc to a blend of polypropylene and polyethylene), which meets the application requirements. Additionally, talc-reinforced polypropylene is suitable for applications where weight reduction is necessary.
