After several years of development, inflatable toys have included a variety of categories, such as inflatable slides, water parks and mobile water parks, etc. The mobility of modern inflatable toys is a major feature because it does not require any site restrictions. As long as the site is flat, it can be operated, and the site can be changed according to the situation. Here we are going to talk about the quality of common inflatable toys. It even concerns personal safety. Therefore, carelessness is not necessary. Rather than make up for it, it is better to prevent it now.
At the connections of the materials, the manufacturer will add an extra piece of material for reinforcement, adding the tear resistance of the material itself, which greatly extends the service life of the inflatable products. At the same time, the PVC sandwich mesh material itself has excellent characteristics such as water resistance, cold resistance (-50℃ to 60℃), flame resistance, and 6P environmental friendliness.
The thread used for sewing is high-strength polyester Bundy thread. Compared with other sewing threads, high-strength polyester Bundy thread has higher tensile strength, good abrasion resistance, low shrinkage, moderate elasticity, and smooth stitches. It can be used in a skilled sewing machine. Under the craftsmanship, the inflatable water slides can be sewn more perfectly.
Both the inside and outside of the product adopt double-thread sewing, and all stress positions such as the corner position, the joint position and the stressed surface must be reinforced with nylon or PVC mesh cloth inside or outside for more than four-thread sewing.
The 10 cm wide reinforced protective strips on the stressed surface are sewn on the left and right sides of the original material. The highest configuration of the six-thread sewing allows the product to withstand long-term continuous bounce pressure.
The stitch length of continuous inflatable water slides is full of mysteries. If the needle pitch is too small, the sewing needle holes are too dense per unit length, and the holes between the holes are easily pulled by the sewing thread. Control the stitch length to 1 inch 4-5 stitches, which is the most reasonable stitch distance.
There are two kinds of special double needles for sewing in the market: 23 gauge needle and 24 gauge needle. In order to speed up production efficiency, most manufacturers use 24-gauge needles, which are thicker, and the force of each needle is large. Although it can save man-hours, it makes the pinholes thicker and reduces the tightness of the product. The manufacturer uses 23 gauge needle on the production line to strictly control the pinholes within a reasonable size, which not only preserves the tightness of the sewn products, but also prolongs the service life of the inflatable toy water slides.
On the back of the product (occasionally on the side), there is a valve flap for quick deflation when the product is stored. The outer side of the zipper is sewn with a zipper cover, and the inside of the zipper cover is sewn with a Velcro to fit together. When the product is continuously inflated, the zipper cover can evenly distribute the pressure of the internal gas on the zipper. The inner side of the zipper is sewn with a safety flap to prevent the product from leaking too quickly under non-human operation, such as sudden power failure, fan failure, etc. This can leave enough time for customers who may be stuck on the product to leave the product safely.
The above inspection steps are not only applicable to common inflatable water slides, but also applicable to large inflatable toys. When purchasing inflatable equipment, please check the product quality according to the above steps.
