All of this material started out generally as plastic pellets. The pellets are feed into one of the massive molding machines, these machines often weigh around 25 tons. The machine heats the plastic until it is liquid. This liquid is then forced through injectors into molds.
First we will explain the difference between a CD-ROM and a CD-R. CD-ROMs are manufactured through the process of Custom Injection Molding Suppliers to form data with a plastic polycarbonate and is referred to as replication. CD Replication is more economical to use on larger run jobs above 500 pieces. CD-Rs are made by using a laser to burn marks in a special dye on a recordable disc and is referred to as duplication. The laser changes the form of the dye, encoding the information into it. CD Duplication is typically used on smaller job below 500 pieces.
Ceramic: These type chips are not 100% ceramic, they are mixed with a polymer to give them added strength. A very important factor to remember about the ceramic chips is that the image is embedded below the surface of the chip and will never fade or peel off. Ceramic Chips have a textured surface and stack very well.
We ended up using a Taco Inc, hot water circulating pump, a motorized ball valve in series with the pump, and an electronic circuit to control the pump and ball valve. A temperature sensor also was strapped to the hot water pipe for sensing the temperature. The Metlund demand system still uses a Taco pump and an electric valve to this day.
The wax is then assembled with other waxes on a tree. Depending on the size of the part, each tree becomes 10 – 200 pieces. After the tree is totally assembled, it is dipped in 5 coats of ceramic slurry.
Among personalized golf gift items, I admit the golf balls are my favorite. Simple, standard 2-piece golf balls usually come in 18-packs and are relatively inexpensive. The cost of golf balls may seem small in comparison to the overall cost of pursuing the sport but the inexperienced golfer can go through a lot of golf balls in a very short space of time!
Along with a strong ferrule, the broadhead must also have durable, thick blades. We should not accept blades that are brittle and break easily. I like blades that have plenty of steel backing them. For a replaceable-blade head, I prefer a minimum blade thickness of at least .025-inch. I’ve found anything less will bend easily and be prone to breakage.
DVD-ROMs and DVD-Rs function similarly to their CD cousins, but DVDs get more complicated in that they can have multiple layers as well as data on both sides of the disc.
