The world of shrink wrap is vast and there are a wide variety of industries that utilize shrink wrap on their products. Due to the varying demands of shrink wrapping, there are a range of different shrink wrap machines and technologies available.Get more news about Auto Shrink Wrap Machine,you can vist our website!
What is Shrink Wrap?
Shrink wrap is a polymer plastic film that is used to cover products. Shrink wrap is applied to tightly fit a product using a heat source that shrinks the wrap to the particular dimensions of the product it's covering. The source of heat is either generated from a hand held heat gun or through a shrink tunnel
Types of Shrink Wrap Machines
For applications that are larger in scale, a handheld heat gun won't cut it for shrink wrapping products. Instead, automated shrink wrap machines are required to shrink wrap products in a quick and efficient manner. Some of the various types include:
Heat Sealers
Regardless of size or scale, most shrink wrap operations use a heat sealer to seal the open ends of the shrink wrap material. Shrink wrap sealers can come in a variety of sizes and forms depending on production needs. The two most common heat sealers for smaller operations are I-Bar sealers and L-Bar sealers.
I-BAR SEALER
An I-Bar Sealer is a shrink wrapper with a single sealing bar that seals the wrap to enclose the product. I-Bar machines are usually found in operations that feature a lower output, as they don't excel at high speeds.
L-BAR SEALER
L-Bar Sealers are shrink wrap machines that are more efficient than I-Bar Sealers, as they function at a higher speed. The L-Bar sealer has two sealing bars in the shape of a backwards L, which is where its name derives from.
Shrink Tunnels
Shrink tunnels are designed for shrink wrap applications that have large operations and are industrial in scale. Shrink tunnels are commonly paired with L-bar sealers to boost efficiency. The heating system of a shrink tunnel far outperforms the heating power of a heat gun, which allows it to handle industrial-level loads. Shrink tunnels are manufactured to operate at semi automatic and fully-automatic speeds.
Stand Alone Fully Integrated Systems
At Douglas Machine, our shrink wrap systems provide a highly efficient and innovative shrink wrap solution for customers with large production needs. As stand-alone or fully integrated systems, our shrink wrappers offer innovative features that maximize speed and easily accommodate large size ranges and pack patterns.
CONTOUR^TM SHRINK PACKER
The Contour shrink packer is a complete integrated machine for loose product collating, tray packing and shrink wrapping. Additional package options make the SPS-Series our most flexible shrink wrap system. With intelligent, adaptable and economical solutions offering advanced heat tunnel technology, superior efficiency and ultimate reliability, our shrink wrap systems meet all facets of today's accelerated production challenges while ensuring your brand is consistently presented with industry-leading package appearance and durability. Our Contour shrink packers can reach speeds up to 150 cycles per minute.

The waterproof microswitch is used a special process to make a sealed structure. So, the water or oil can not easy to fill into the inside to lead to snap action switch a short circuit. Generally, we have the IP64 and the IP67 protection level for options.Get more news about Best Price Waterproof Micro Switch,you can vist our website!
Besides, it not only can resist the water but also the dust as well.
Our G9 and G5W11 also have explosion-proof certification, like the ATEX. The explosion-proof micro switch has a very potential market prospect.
The Water Proof Micro Switch Application
Our switches can supply safety protection for many parts of appliances and equipment, such as a car lock, EV charge, Humidifier, Coffee machine, washing machine, Water pump, and so on. If a switch with a rubber band on the pin plunger and a waterproof coating around the item surface so it may belong to the water proof switches. If not, they may not belong to the waterproof type.
Zing ear G3, G5W11, G905 and G10B series are both belong to the water proof microswitches with UL, CUL, ENEC, and CQC certificates. Meanwhile, because of the years of experience in switch research and development, the product quality is reliable. They not only can replace Omron, Honeywell, Marquardt, and so on, but also have a competitive price for buyers.

CPI Waterproof Switches have been solving tough engineering problems for over 50 years. Our switches perform flawlessly under severe environmental conditions where traditional splashproof, weatherproof, or wash-down resistant sealed switches do not survive.Get more news about Best Price Waterproof Micro Switch,you can vist our website!

Our switches are truly waterproof. Used in tough military and industrial switch applications, we stock a wide variety of switch types, as well as an engineering team that can provide complete customization of your waterproof switch solution.

For reliable operation under exposure to water, oil, humidity, sand, dirt, vibration, shock, and temperature, CPI'w waterproof switches get the job done.
What Makes CPI Waterproof Switches Unique?
Our switches are really designed for control and sensing applications in outdoor equipment. They can be hand actuated, or placed in one of our many mounting brackets for mechanical actuation. Our unique advantages boil down to a few key points

1. Extremely high endurance. Think no in-warranty field failures. Depending on the switch and the electrical parameters, we have endurance ratings as high as 5 million cycles.

2. Small Form Factor . With our wide variety of mounting brackets, and small footprint, our switches can fit into tight spots.

3. Extended Temperature Range - Near the blazing heat of an engine block, or in the freezing cold depths of a navy submarine, our switches continue to perform.

CPI's waterproof momentary switches are truly waterproof, not "splashproof" or "water resistant". These sealed switches feature a unique manufacturing process which seals both the switch and the lead connections making the assembly extremely durable, and capable of extended electromechanical endurance ratings up to 5 million cycles. Our pendants can be customized for the right tactile feel for manual operation, or mounted in one of our many mounting brackets to achieve durable limit switch operation in your equipment.
