The general water bottles are round and sometimes take space in the bags, but these water bottles are square. If they are placed properly, they can save a lot of space inside your bag.

Spray cap molds are used in the molds for producing insecticide shells. They are made in accordance with the shape of the insecticide cover required. They are injection molded with plastic and processed into insecticide shell parts through various processes. The principle of the spray tank is that the liquid is pressed out of the valve by using air pressure. The liquid can be sprayed evenly. The direction and dose can be controlled. Any content can be easily put in and easy to use.

Most of the plastic flip top caps mould are designed with two-time ejection structure. The core is pushed out two times. The stripper plate and the ejector sleeve in the middle of the product are pushed out together to 14mm, and then the stripper plate push out continually until the flip top caps drops.

Each cavity of this cap mold is designed with separate inserts, so that each cavity product in the process of injection molding maintain the same injection molding pressure, clamping force and other molding conditions, so that the product quality is more stable and reliable. Moreover, the independent insert design can make the life of the mold longer. If there is any problem with the parts, the parts can be directly replaced without affecting the production schedule.

The unscrewing device of this cap mold is hydraulic motor. The ejecting sequence of this cap mold is to let the upper press plate open the mold first, and rely on the I-shaped block to drive the cavity slider to slide away. The mold is opened to a certain stroke, and the caps will be unscrewed by hydraulic unscrewing motor. The left and right thimble plates are performed simultaneously. The spring is pushed out of the barrel by the force of the spring, so that the product is firmly in the core part. After opening the mold, the oil cylinder pushes the rack, drives the central drive shaft, drives 4 product threaded shafts backward to disengage the product, and then relies on the 2 ejector rods on the outside of the machine, and the ejection plate pushes caps off from mold.

Flip top shampoo cap is one-time use of large-scale production product. Normally, after injecting, there is no more surfaces processing, and it can directly enter the subsequent automatic packaging. Therefore, the appearance of the flip top shampoo cap is required to be high, and there are no obvious molding defects.

The cap of salt shaker is combined with lid and cover. There are two holes on lid for fixture of cover, which lid mold shall be designed with lifters. The neck of lid is necessary to design sliders before being ejected out from cavities. This design is to protect the thread of lid and avoid damage by force ejecting. Briefly, the lid looks simple and common plastic part, the mold design is more complicate.

Plastic liquor caps are different from the ones we usually use. They are not sealed by threads or barbs like plastic caps of mineral water bottles, but by oak plugs. However, the oak plugs may cause decay or cracking after long-term and long-distance transportation or weather, plastic caps are needed to keep them sealed and protect oak plugs.

The plastic raw material of 5G cap is LLDPE, which has high gloss, high heat resistance and better fluidity than the general materials. In addition, the steel of mold core and cavity is S136, with a hardness of 48-52, which can better for mold life. It could be design with 12 cavities or 16 cavities, each cavity has its own independent cooling system to ensure that the products can be better shaped and cooled.
