How are the suitcases that are prepared in every household made? In a factory that produces suitcases, these blue spherical particles are actually the raw materials for making suitcases. After the machine is turned off, the nozzle sprays the melted liquid of these particles. After opening, a suitcase shell is completed.

First, workers pour the colored particles and white particles into the mixer, and the machine mixes and melts them thoroughly, turning them into a viscous blue liquid. The wood-building machine then shoots the polypropylene liquid after the model is closed, and the machine's cooling system causes the polypropylene to solidify in an instant, turning it into a clear and durable suitcase shell. The casing is then sent to the next station, where the worker affixes the brand logo to the notch, secures it firmly with a hydraulic press, installs the handle, and installs the side corners on the bottom of the suitcase, where he can The suitcase stands more stable. Once completed, workers placed the other half of the shell on top and connected the two halves together with a stainless steel rod.

Second, the next step is to make the suitcase's stabilizer. The machine moves the nylon wheel hub under the mold. After the mold is closed, the nozzle injects liquid rubber onto the surface of the wheel hub. The rubber adheres to the wheel hub and does not slip. . Then the workers installed the two wheels on the bracket, and the workers on the other side installed the telescopic handle on the suitcase and fixed it with a metal bracket inside the suitcase, which can greatly improve the smoothness of the telescopic handle. Then insert the wheels into the bottom of the suitcase and reinforce it with screws. The suitcase with four wheels can rotate 360 ??degrees. A worker then embeds the waterproof strips into the edge of the case, then installs the buckle bracket and combination lock.

Third, there is a zipper bag storage lining door. After fixing it with screws, buckle the elastic buckle bag on the bracket. After everything is completed, the workers will randomly select a suitcase for testing. The workers will put it into a stainless steel roller suitcase and keep rolling it inside to ensure that the suitcase can withstand rough enough operations. Once testing is complete, the suitcases will be ready for sale.
