One day, I brewed milk powder for an 8-year-old child. The child was in the growth stage. He looked at the milk powder can, his eyes full of doubt and looked at me and asked: Mom, how are these milk powder put into the can? So many people have to drink milk. How many cans must be filled every day to meet the needs of these people? And the milk powder powder, how to prevent the powder from flying, and so on.
I thought about it for a while, why the children have so many questions. Fortunately, I am engaged in the filling production and packaging line industry, and I can still answer these questions.
Let me briefly describe to the child: because there is a production line for fully automatic filling, sealing and capping of milk powder. The entire Milk Powder Can Filling process.
The specific operations are as follows:
1. Put the milk powder cans on the bottle feeder, and the bottles will enter the empty cans sterilization and blowing machine in an orderly manner.
2. After sterilization, the milk powder is conveyed to the double-head screw powder filling machine through the feeder for filling milk powder.
3. After the milk powder is filled into the milk powder tank, it enters the vacuum nitrogen filling machine for sealing.
4 Enter the tank cleaning machine to clean the tank, and then record the production time and other information through the laser printer.
5. Flip the lid through the can turning machine, send it into the long conveyor belt, enter the capping machine, and do the capping, so that a can of milk powder is perfectly completed.
6. Finally, the carton is packed by carton opening machine, sealing machine, strapping machine, and palletizer, and then sent to all parts of the world.
PC and PMMA are two commonly used transparent material for CNC machining. In appearance, the difference between the two types of prototypes are not obvious, but the transparency is not the same actually. Now let's talk about the advantages and disadvantages of the two materials.
Polycarbonate (PC)
PC is the abbreviation of Polycarbonate, it’s an almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resins have high toughness and temperatures are approximately 130 °C.
Advantages:
• High strength and elastic modulus, high impact strength and wide range of temperature.
• High transparency and free dyeability.
• Low forming shrinkage, good dimensional stability.
• Good fatigue resistance.
• Excellent weatherability.
• Excellent electrical characteristics.
• Tasteless and odorless, harmless to the human body, in line with health standard.
Disadvantages:
The main performance defects are insufficient hydrolysis resistance, sensitivity to the notch, poor scratch resistance, and it’s easy to getting yellowing when exposed to ultraviolet light for a long time. Like other resins, PC is susceptible to immersion by certain organic solvents.
Application:
• Optical illumination
It is used in the manufacture of large lampshades, protective glass, optical instrument eyepieces etc. It can also be widely used as a transparent material on aircraft.
• Electronic appliances
Polycarbonate is an excellent insulating material used in the manufacture of insulated connectors, coil frames, pipe sockets, bushings, telephone housings and parts, and battery cases for miner's lamps. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, electronic computers, video recorders, signal relays and other communication equipment. Polycarbonate films are also widely used as capacitors, insulating bags, audio tapes, color video tapes, and more on.
• Mechanical equipment
Used in the manufacture of various gears, worm gears, bearings, bolts, levers, crankshafts, as well as parts such as mechanical equipment housings, covers and frames.
• Medical equipment
Cups, cans, bottles, and dental instruments, drug containers, and surgical instruments that can be used for medical purposes, and even artificial organs such as artificial kidneys and artificial lungs.
• Other
PC in the construction field is used as a greenhouse glass, etc.; for daily use, it is used for bottles, tableware, toys, models, LED lamp housings and mobile phone casings.
Polymethylmethacrylate (PMMA)
Polymethylmethacrylate (PMMA), also called Acrylic or organic glass, Lucite (trade name), is an important optical plastic. It has good overall performance and optical properties, transparency comparable to optical glass. It can hardly absorb the full-band light of visible light, the light transmittance is more than 91% with good gloss, strong lightness and good molding processability, the chemical resistance and weather resistance are outstanding. The disadvantage is that the surface hardness is low which is easy to scratch and expand by absorbing water.
Application:
Acrylic is mainly used in the construction industry for architectural lighting, transparent roofs, roofs, telephone booths, stairs and room wall panels; sanitary wares include bathtubs, washbasins, dressing tables and other products. The application development of highways, high-grade road lighting covers and automotive lamps is also quite fast. Among them, the market for building lighting, bathtubs, street advertising light boxes and telephone booths has grown rapidly. It`s has lager space for developing in the future as well as the market prospects are very broad.

In a jewelry store setting, the same concept applies of drawing customer to your most high margin items.
Typically, jewelry stores use jewelry display showcases in the main part of the floor to showcase necklaces, watches and bracelets, and usually gemstones. This is because in most cases, customers are going to shop for diamonds, which are always in the back parts of jewelry stores, drawing you past all the rubies, sapphires, and gold.
It’s the same concept of putting the most sought after and high volume items in the back. It draws customers past all the high margin jewelry like necklaces, bracelets, giving you a chance at an extra sale. It’s also a free flowing layout to help keep an eye on customers by allowing for good visibility of what’s happening in the store.
Some jewelry stores also use top-of-counter displays to showcase lower priced jewelry and items that bring higher margins. Then, more expensive pieces are placed in the case underneath them.
Another important point to consider when merchandising items in jewelry stores is lighting. Make sure that you are using the proper lighting to enhance your products, both inside and outside of the store display cases.
