There are two main types of charge structure, continuous charge and segmented charge (spaced charge). When the explosive is filled with the blasthole, it is said to be uncoupled (see Figure 1 (É‘)). When there is a certain gap between the explosive and the wall of the hole, it is said to be uncoupled (see Figure 1(b)). Spaced charges (shown in Figure 1(c)) are generally separated by air or stuffing. The former is generally used in ore-rock below medium and hard, and the interval charge can be adjusted according to the parameters of the blasthole and the condition of the rock through it. The length of the charge and the local blasting energy reach a better blasting effect.

Fully Automatic Blister Forming Machine

Fully Automatic Blister Forming Machine applications

1.  Fully automatic blister forming machine is suitable for materials like PVC, PE, PET, PC,PP, HIPS, APET, PETG, PS, and so on .

2. This machine can transform plastic sheets into various plastic holow shells for packaging applications like: Toys, hardware, foods,

    stationery, electronics products, etc.

Advantages of Fully automatic Blister Forming Machine

1. This machine adopts Mitsubishi frequency Motor tap piece, pull tab faster, easier to adjust, and the exact length of the pull tab, reduce material and energy consumption, improve product quality.
2. Independently grouped temperature controlled..
3. The furnace temperature using a digital independent regulator, point by point display, and each control table with separate regulator         system, completely solved due to voltage fluctuations caused by the product quality problems.
4. Digital DIP intelligent regulator monitors, visual stability and achieve the digital management products produced at the same time to           facilitate the process of generation of process monitoring.
5. In the first products of normal production, simply complete record production process parameters during down time after the customer       repeat orders, production parameters recall previously recorded data, you can produce high-quality products, to achieve a shape, reduce unnecessary waste. (Touch-screen machine)
6. Double row needle chain transmission, high-speed operation is stable, flexible width adjustment device, can make the machine more         maximum use of film, improve product quality, reduce material loss. 
7. The machine is equipped with a cooling system and high-speed transport water spray cold water to make it accelerate the forming             speed and forming quality assurance, production twice as fast as conventional machines.
