UPS says the trucks are working out very well for the company, and have shown to be very durable, are easily repairable, and work well in nearly all climate types. This is good for the company because many trucks that operate in corrosive environments (such as areas that are typically salted during the winters) often need body maintenance to prevent rust, and these new plastic trucks are rust proof. These trucks are also very easily repairable because the plastic body panels are all modular. The floors of these new trucks are still metal, however, to support the weight of all the packages that the trucks must haul.

The Servo Hybrid is a new line of plastic machines from Cincinnati machines that successfully does what many in the industry have been trying now for almost a decade to do: Make a hybrid moulding machine that isn't completely worthless.
The new Servo hybrid line from Cincinnati Machines features three new machines: the Maxima Servo, the Magna T Servo, and the VITESSE. They are quite impressive machines, with their new servo-hybrid technology offering versatility, precision, energy efficiency, reliability, and user-friendliness. Supposedly this new servo-motor technology combined with an efficient internal gear pump reaches the operating efficiency of an all-electric machine.
Now, I totally believe Cincinnati Milacron on this one, because if anyone could do it it would be them, but that is a mighty tall claim coming from a little baby hybrid machine. I will have to see it to truly believe it. But from what I have read, the technology is definitely there to back it up. The new servo-motor that they have designed is supposed to be the real deal: it apparently allows for much increased repeatability, up to twice as fast as other machines, and up to half the energy consumption. That is a lot to brag, but it is almost expected from the likes of a Cincinnati Machine these days.

The vast industry of injection molding machines is widespread throughout the world, but there is a distinct hub of the industry in China. This could be thanks to the Chen Hsong Group established by Dr. Chiang Chen in Hong Kong during 1958. The company began as nothing more than a small machinery workshop, but after striving for excellence and creating quality products for half a century, Chen Hsong is now the largest manufacturer of injection molding machines in the world.
Spreading sales across sixty-five countries, including China, Taiwan, the United States, Canada, France, the United Kingdom, Brazil, Argentina, and Mexico and in most of the southeastern Asian countries, Chen Hsong has proven their worth amongst the best in the business. This is no small task seeing how injection molding has become one of the most competitive industries in the world, so the demand for the machines has increasingly risen. However, through it all Chen Hsong has been recognized for their devotion to quality and through this devotion, they have gained respect.
Chen Hsong serves its faithful customers 24-hours a day, 365 days a year for sales, maintenance service, and troubleshooting, which cannot be said for every company.

The amount of plastic produced in one day varies from each type of machine in various industries. Some molds for plastic injectors are multi-cavity molds, which can make one hundred products at a time, so thousands can be produced in one day off a single high-production machine. By minimizing the time from when the plastic starts melting, to injecting it into the mold, to waiting for it to cool, and finally, ejecting the finished product from the mold will give a machine and the operator their total maximum output.
When waiting for the mold to cool it is necessary to scrap the excess plastic from the hardened yields. Carefully controlling the plastic temperature, the pressure and rate as the mold fills, and how quickly the mold cools are variables to reduce the amount of problems during the injection process. The rate at which the mold fills must be as fast as possible to reduce the chance of the mold hardening before it has been completely filled.
Note: The product size effects the amount of plastic produced on a given day, e.g. a milk carton cap will take less time to process than the bumper of a car.

The cost variance when buying raw plastic is really going to depend on the type, quality, and grade of the polymer material being used, i.e. some are hard plastics and some are pliable. Buying raw plastic in bulk—as with most other things—will cut costs and be very affordable for everyday use. If the raw plastic is being bought up for repeatable production say in a factory, go bulk, but for the everyday injection hobbyist, bulk might be a bit excessive.
Many bulk, raw plastic providers require minimum orders of at least one metric ton of material, which will generally run from one thousand to two thousand dollars depending on the type of polymer purchased. These bulk orders can be bought in a variety of high-concentrated pigments, and they’re typically odorless and nontoxic. Re-processed, or recycled materials will also reduce raw material costs if this is something you might consider. The same goes for none-bulk purchases if you’re simply injection molding as a hobby. For ten ounces of raw plastic, dependent on the grade, costs will usually be about ten dollars, which is quite a reasonable price. Finding raw plastic providers on the Internet is easy and only a click away.

Hobby injection molding, also known as bench-top injecting, is carried out by producing molds on smaller scales than in an industrial plant or factory setting where mass production of products is the goal, but rather it provides a low-cost alternative for repeatable creation. A good example would be making homemade golf tees. Injection molding has become cheaper and more affordable for hobbyists over the years, and can be easily handled by one person. These bench-top injectors are beneficial to inventors hoping to make new prototypes from their workshop or garage, which cuts the costs of hiring someone else.
A bench-top injector is simple to use and isn’t overly strenuous. Most injectors of this type have a single lever that is pulled down to manually engage the injector toward the mold to insert the polymer. The best way to ensure that the two halves of the mold are pressed tightly together is to clamp or bolt them together, thus reducing the amount of defective products, and saving money on raw material costs. There are four different mold types to choose from: epoxy casting, pressurized mold casting, degassing mold casting, and single use molds. Also, to harden the polymer quickly think about keeping the molds at a cool temperature before use.
