here are two basic types of self adhesive labels: permanent and removable. Each type of adhesive is made from a variety of glues depending on the conditions the label will have to endure, the length of time it is required and the environment or conditions of storage.
Self Adhesive Label use glossy paper, matt material to print CMKY color. It is print by oil, it can be also add series number, QR code, scratch off part in self adhesive label.
Kindly see below self adhesive label, which we can accpet OEM label.
Just need your logo in AI, CDR, EPS file, tks.

Self Adhesive labels are usually coated with an acrylic, rubber or water-based glue. Sticky labels can either be applied permanently or temporally.
Self adhesive labels can printed on by laser printers, inkjet printers, photocopiers or handwritten. Laser printers and photocopiers are a hot process and we recommend that A4 sheets of labels are only printed once for best results. The heat process evaporates the moisture in the adhesive each time it is passed through the printer.
Design of Valve Controller Based on Pro / E5.0
1 Overview With the development of industrial automation, the traditional way of manual mechanical adjustment is no longer applicable in many occasions, in order to achieve industrial automation network management system, can not do without automatic valves in the pipeline system of implementing agencies. There are also many types of valves. The following model is one of them - a ball valve, as shown in Figure 1. Due to the wide range of valve applications, the manual mechanical adjustment method is no longer suitable for many applications. The design can work under safer conditions and improve the efficiency by several times. Therefore, the design of intelligent valve control device has the practical significance. Electric actuator is a very important field drive device in industrial process control system. It has convenient access to energy and simple installation and commissioning. It has been widely used in power, metallurgy, petroleum and chemical industries. 2 Principle The valve controller is driven by a motor and decelerates through a worm gear to drive the hollow output shaft to rotate. In this gearbox, there are manual / automatic mechanism (manual mechanism can operate independently). When the switch handle is in the manual position, operate the hand wheel to drive the hollow output shaft to rotate. When the actuator is operated electrically, the manual mechanism is turned off and the hollow output shaft is driven by the motor. The details of the transmission mechanism shown in Figure 2. Figure 2 transmission structure Figure 3 Turbine worm design Because the worm here have special requirements, so their own design and verification (here with special software design). The design of the worm is only the spiral part. According to the inventory of materials, and taking into account the worm power transmission is not large, medium speed, but the worm in the transmission play a very important role, so the worm with 45Cr; hope higher efficiency, better wear resistance, so the worm Spiral tooth surface requires quenching, hardness 45-55HRC. Worm with ZCuSn10P1, metal film casting. After the completion of the design of the model shown in Figure 3: Figure 3 Worm Worm various parameters are as follows: Worm input power: 8.05kW Worm type: Archimedes worm (ZA type) worm speed n1: 1460r / min worm speed n2: 73r / min Life expectancy: 8000 hours Theoretical transmission ratio: 20 Number of worm head z1: 2 Number of worm gear teeth z2: 40 Actual gear ratio i: 20 ************ Worm and worm gear material ********* *** Worm material: 40Cr Worm heat treatment type: Quenching Worm material: ZCuSn10P1 Worm wheel casting method: Centrifugal casting Fatigue contact strength Minimum safety factor SHmin; 1.1 Bending fatigue strength Minimum safety factor SFmin; 1.2 Rotational speed coefficient Zn: 0.749 Life expectancy Zh; 1.21 Material elastic modulus Ze: 147N ^ 0.5 / mm Worm material contact fatigue limit stress σHlim: 425N / mm ^ 2 Worm material allowable contact stress [σH]: 349.914N / mm ^ 2 Worm wheel material bending fatigue ultimate stress σFlim: 190N / mm ^ 2 Permissible Bending Stress of Worm Wheel [σF]: 158.333N / mm ^ 2 ************ Calculation of Worm Wheel Material Strength ************ Worm Shaft Torque Worm shaft contact strength requirements: m ^ 2d1 ≥ 1161.145mm ^ 3 modulus m: 5mm worm points Degree of circle diameter
