What is the service life of silicone? Will it break? Do I need to worry about dry rot? Silicone rubber does not dry out like rot. Silicone rubber is the longest-lived of all rubbers or elastomers. Five years of shelf testing has shown that its performance loss is less than 10%. With proper care and maintenance, your real sex doll can be used for many years. After 11 years of service, there are still first generation silicone dolls that are being used and loved. As long as your sexy love doll is properly maintained, it will continue to be used.

What are the characteristics of silicone? What should I pay attention to? Can I be allergic? Our premium silicones for adult doll products are also used by the film special effects industry for makeup effects and animated animals. It has a high degree of flexibility and tear resistance. The specific formula used by TPE dolls contains harmless oil suspended between silicone molecules, making the pulp more realistic and more elastic. Silicone skin may feel a little tacky because its surface area sweats very little oil. This condition will gradually decrease over time, and we recommend that you use baby powder or talc to remove any stickiness. You may be allergic to baby powder than silicones. We have never received reports of negative health effects on our silicones-it is inert and non-toxic when used as directed.

Features and special options. Does the doll include any electronic features that enhance the enjoyable experience, such as a vibrating vagina or a rotating tongue? Sex dolls do not have electronic functions, such as a vibrator or a rotating tongue. We believe the use of vibrators can make artificial vinyl vinyl dolls vibrant, but silicone dolls don’t need to. However, if you enjoy extra excitement, TPE masturbation dolls work well with such devices. You can use any sex toy your doll can imagine in a very realistic way. Silicone can transmit vibration well.

Do you make BBW or chubby dolls? Can I get a doll without seams? No, due to the way the doll is molded, it is impossible to make a doll without seams. Our technicians carefully trim all seams by hand to keep them as low-key and unobtrusive as possible. What is a hair patch made of? We use custom patches that are human hair knotted by hand on a very fine mesh background. The mesh helps the hair adhere to the silicone with the silicone adhesive we use. The patches come in 4 standard sizes and 5 standard colors-black, light brown, russet, red and gold.

Can I stick my hair on the doll myself? Yes, you can order more hair accessories and adhesives from us to apply to your mini sex dolls. Can I disassemble a doll with pubic hair or other body hair? Although the hair will fall off over time, it cannot be removed because it sticks to the doll’s silicone skin. If the pubic hair is removed, there will always be scars on the silicone.

Can I get a doll with chest hair, pubic hair, or armpit hair? Yes, we can put some extra hair accessories on the doll, but this is generally not recommended. Usually, the hair piece will fall, especially in high friction areas under the arm. Do you offer transgender dolls? Transgender dolls are available in 3 different versions with latex dolls. You can view options and fees for male dolls and products on our page. If you want a product that differs from our options, we have done custom hermaphrodites / dolls in the past. If you have special requirements, please contact us.

Can you press the doll’s breasts together to form a deep crack? Yes, it depends on the body type? Smaller breasts are not suitable for this type of activity. The breasts of real sex dolls are very elastic and supple. Do you offer custom breast sizes? Cheap silicone dolls‘ breasts are not individually connected; they are a seamless part of the entire body. However, we can do breast augmentation surgery. Breast enlargement doubles your breasts. For example; a B cup breast will become a C cup breast. You can choose this option on our order page.

How hard is the doll’s nipple? Will they wear clothes? Erotic doll nipples are very much like real, upright nipples. They show through clothes. Can you pull or bite the nipples of a love doll without worrying about tearing? Yes, within a reasonable range. High-end adult dolls can withstand about 400% elongation before tearing. If it is too rough, pulling or biting on your nipples may cause them to fall off.

How real is the breast on a real cheap doll? We use special silicone formulations with gel consistency. Love dolls use this special silicone inside their breasts to make them look, feel and bounce like real breasts. Silicone gel is cured silicone rubber and is completely dry; it is not liquid, so the breasts of sexy adult dolls do not leak. Usually, when your doll arrives, the breasts will be a little stiff, but they will soften over time.

Can I pierce the doll’s ears, nipples, etc.? Yes. You can pierce life size sex dolls anywhere. For best results, always use straight jewelry instead of curved bars. After a few days, the perforation will become permanent. When using earrings, do not use the back of the earrings.

Are there tan lines or tattoos? Sepia threads can be used on silicone sex dolls. This is a custom process that requires lighter skinned dolls with tanned patterns. You can select this option on the order page. Customers can apply tattoos using temporary tattoos available in many stores. We also completed custom tattoos for special orders. These prices depend on the complexity and level of art required. In the case of tan lines and tattoos, the color will be wiped off with friction over time, because silicones are not inherently colored during these processes. Contact us for more information about tattoos, freckles, birthmarks or other application details.

What’s the difference between love doll sex magnetic and full head face? The magnet type face is designed to quickly change your doll face to another magnet style face using our patented hi-tech system. In this design, there are seams between the face and the back of the head, and you won’t see the seams unless you remove the doll’s wig. The hat on the doll’s head is made of lightweight foam to save weight. This style has many different faces to choose from, and they are all interchangeable. Changing faces is easy, fast, and requires no tools.

The full-head-style face is permanently attached to its individual skull, so the price is slightly higher. The main advantage of this design is that it can free our artists from the size and shape of the existing X-face skull, that is, when we want to create a larger or smaller head or different skeletal structure. There are also no seams or separations between the face and the rest of the head because they are all silicone. As a result, they are slightly heavier than magnetic surfaces. The full head can be removed with an Allen wrench.

You can set up two types of gimbals for real love doll. Use magnetic skulls and hats to highlight this type of face and wear a full head shape when needed. The connection points on the fuselage are the same as the hardware.

substance is the raw material for many sex dolls

Realistic sex doll provide high-quality synthetic wigs that can be removed for styling, cleaned or completely replaced with any commercial wig. When brushing long wigs, it is best to use a metal brush or comb and start brushing a small part near the ends of the hair. Brush off the hair about 3 inches from the end until it is smooth, then gradually move up the wig towards the scalp. This will avoid tangling wigs. Synthetic fiber wigs are easier to maintain than human wigs.

Are there known health risks? How difficult is it to keep a lifelike love doll hygienic? There are no known health risks associated with sexy sex doll products. After manufacturing, each silicone adult doll will receive a thorough acetone bath. Keeping your doll hygienic is easy-you can clean the doll with a mild soap or detergent. Each TPE love sexy doll comes with a cleaning kit and easy-to-follow care and use instructions.

Blend dolls are a combination of multiple choices that span multiple doll rows, making unprecedented combinations possible. For example, pick up the silicone head and attach it to the main body of a TPE love doll or the main body of a sex toy series. Although not all combinations are possible, most combinations are available. So if you see your favorite face and your favorite body, which happen to come from different lines of our doll, please let us know and we will do our best to make this combination work.

A Brief Introduction of the y Swing Check Valve

The y swing check valve is also called a one-way valve or check valve, which is used to prevent medium backflow in the pipeline. The opening and closing parts are opened or closed by the medium flow and force to prevent the medium from flowing back. The valve is called a check valve. Check valves belong to the kind of automatic valves, which are mainly used in pipelines where the media flow in one direction. Only one direction is allowed to flow to prevent accidents. Valves of this type shall generally be installed horizontally in pipes.


  1. Product Description

The y swing check valves are used in pipelines with a nominal pressure of PN1.6-6.4 MPa and working temperature of – 29-550 C in petroleum, chemical and thermal power stations.


Applicable medium: water, oil, steam, and so on.


The y swing check valves refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent medium backflow, which is also known as a check valve, one-way valve, counterflow valve, and back pressure valve.


The check valves are an automatic valve that is used to prevent the backflow of the medium, the reverse of the pump and drive motor, and release of the container medium.


Check valves can also be used in pipelines to supply auxiliary systems where the pressure may rise above system pressure. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).


2 Main Structural Characteristics

The y swing check valves adopt the structure of the internal rocker y swing. All the opening and closing parts of the valves are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and ring used in the middle flange part, there is no leakage point, on the whole, to prevent the leakage of the valve. The y swing check valve rocker arm and valve disc connection adopt spherical connection structure, so that the disc has a freedom angle within 360 degrees, with appropriate micro-position compensation. The y swing check valves of Huande Steel Valve have been widely used in chemical, metallurgical, pharmaceutical and other fields. Check valves are generally suitable for cleaning media, not suitable for media containing solid particles and high viscosity.

Advantages and Disadvantages of 630W Ceramic Metal Halide Lamp

The biggest advantage of 630W ceramic metal halide lights is that its luminous efficiency is very high, and its luminous efficiency is as high as 80-90Lm/W. It has less heat when luminous normally, so it is a kind of cold light source. Because the spectrum of metal halide lamp is a dense linear spectrum superimposed on the basis of continuous spectrum, the color rendering index is particularly high, that is, the color reducibility is very good, up to 90%. In addition, the color temperature of metal halide lamp is high, which can reach 5000-6000K, and the special projector lamp can reach 7000-8000K. Under the same brightness condition, the higher the color temperature, the brighter the human eyes feel.

Ceramic metal halide lamp has short relative life because of its high brightness and small volume. Due to the limitation of material and technology, another disadvantage of metal halide lamp is that it is difficult to start, so special trigger must be used. The brightness system increases gradually after starting. If the starting energy is too large and the starting speed is too fast, the lamp life will be affected. Full consideration should be given to the circuit design.

The disadvantages of 630W ceramic metal halide lamp are as follows:

  1. Can’t open again after extinguishing (wait 3-5 minutes);
  2. High power consumption;
  3. Ballasts are needed (relatively heavy);
  4. Life is shorter than that of LED.
  5. High temperature is generated at the ignition point, and protective cover is required.

According to the shortcomings of 630W ceramic metal halide lamp, choose the suitable lighting lamp.
