Project Background

The client is the purchasing manager of a company specializing in the design and manufacturing of outdoor products. They are committed to providing high-quality thermos bottles, and they focus on product innovation and functionality. In order to meet the customer's demand for high-strength bottle lids, they cooperated with us, hoping to design and manufacture a high-quality outdoor thermos bottle cap.

Material Selection

Customers require bottle cap materials to meet food-grade standards to ensure product safety and hygiene. To meet this requirement, we selected PCTG material, which is certified to meet food grade standards.

At the same time, PCTG materials also have high strength and excellent impact resistance and can withstand certain external forces and pressures without being easily broken or deformed.

Injection Mold Design - Cooling system

The customer's product design is relatively thick, and we need to avoid product shrinkage while ensuring the thickness. In order to solve this challenge, our mold engineers designed a good cooling system after discussion, and at the same time ensured sufficient cooling time by controlling the injection molding parameters. Through these efforts, we successfully avoided product shrinkage and ensured Product appearance and quality.

Product Thread Design

The customer's bottle lid design adopts a threaded structure, which requires that when the cap is tightened, the cap and the mouth of the bottle can be tightly sealed to achieve the effect of watertightness. In order to achieve a good fit, we also recommend placing several waterproof rings. Through multiple tests, we ensured the perfect fit between the cap and the bottle, effectively preventing water leakage.

Surface Treatment

Alpine mold provides one-stop service, including mold design, manufacturing, injection molding, etc. At the same time, we also provide product assembly and surface treatment services, such as silk printing, painting, polishing, electroplating, etc. For texture, we have designed a set of texture boards for customers to choose. This product has made the surface of texture, and the pattern is VDI 36.

Customized package

At the same time, we provide customers with personalized customized services, such as customized packaging, customers provide our packaging design drawings, and make product packaging according to customer requirements.
