It’s admired for its durability, stretchiness, and ability to waterproof just about anything. These attributes make it an excellent compound for a variety of applications. Ever wonder where it comes from and how we transform it from its most basic form into our beautiful rain boots?
The process of making Children rubber boots is less complicated than you might think...
STEP 1: Natural rubber latex, or just rubber, is collected by creating slits in the bark of a rubber tree. The sap that is drawn from these slits is sticky and milky in texture and collected in a bucket where it is allowed to harden.
STEP 2: The rubber is then processed by removing excess water and mixing it with other materials, creating our rubber compound.
STEP 3: The rubber sheets are hung to dry.
STEP 4: These dried sheets are stacked, compressed, and sent to... less

Denim Heat Transfer Film process principle and heat transfer paper similar, only the heat transfer film substrate or transfer media is transparent film, the bottom membrane material is mainly three kinds of opp, PET, PVC.
1. OPP: larger flexibility, larger impact pressure, but poor heat resistance.
2. PET: low flexibility and good stability. The most widely used. 80% of the heat transfer film is made of this material.
3. PVC: corrosion resistance and good insulation.
We are one of the heat transfer label manufacturers and welcome to your come and purchase! less

In plastic injection molding, gate design is critical to achieving molded part quality and productivity. Because gates are designed to allow melted plastic resins to move into the mold cavity, it’s imperative that gate material, size and location are optimized for structural, operational and aesthetic considerations.
Material
Proper material selection is critical in plastic injection molding gate design. The last thing you want is the wrong material based on machining a part from a stock resin that’s been cast into bar stock or flat stock.
Castings are always stronger & less prone to stress fracturing. A part machined out of cast material will often give you a resulting stronger part. If machining the part includes sharp corners, this could become a trap into the material selection being completely wrong for the molding process.
Size
Gate size will depend on the resin being used and the size of the part being... less

However, there are times when it is necessary to use a jack horizontally. Projects such as aligning a door frame benefit from using a winch to spread the opening. Bottle jacks are the only ones that work this way. Using a hydraulic jack in a horizontal position requires the pump to be lower than the piston. This prevents the hydraulic fluid from escaping into the piston accumulator and causing a pressure drop.
Step 1
Turn the drain valve counterclockwise using the notch on the end of the lift handle to fully lower the piston. Turn the valve clockwise as soon as the piston points down.
Step 2
Place the jack on the side with the pump under the container. The reservoir is the cylinder containing the piston and the pump is where you insert the handle.
Step 3
Hold the jack with one hand in a straight horizontal position and operate the pump with the handle. Pump the handle side-by-side until the base of the jack and the surface... less

Jersey (viscose, cotton, tencel etc); college; french terry; interlock; ribbing; and so on... These fabrics are so much fun to sew! We'd say they are more forgiving than non-stretch fabrics since the sewn garments will shape with the body.
Knit fabric doesn't fray, which means that you don't have to finish seams, which you would do with woven fabrics. Neither does knit get wrinkly, as much as woven fabrics usually do. They do shrink when washing for the first time, so you'll want to pre-wash the fabric before cutting into it.
Knit fabrics can have different amounts of stretch. For example, generally ribbing has a lot of stretch, while jersey and interlock has less. But it depends on if and how much lycra is in the fabric. Find more info in our fabric guide (coming soon).
It's a good idea to evaluate the stretch of the fabric before sewing. For some sewing patterns the amount of stretch needed in the fabric is... less

The custom rain boots are made from natural rubber, which is a durable and soft material. Natural rubber is 100% waterproof and supple. This makes the rain boots flexible, comfortable, and easy to wear and walk around in.
Rain boots with both wide and narrow shafts
Our rain boots are designed in line with today's trends and fashion and come in many different colors as well as a variety of details and patterns. We sell rain boots for boys and girls, big and small. Our rain boots are designed to have a great fit while providing support and stability to the feet. We make rain boots with narrow as well as wide shafts. This ensures that your child can walk around naturally in their rain boots and that wearing them does not hinder their play or ability to walk.
Room for growth in rain boots
When buying rain boots for your child, avoid buying ones with too much room for growth as rain boots cannot be strapped to the foot in the same way that other footwear can. If the... less

Use special thermal transfer ink to print various patterns on special types of paper, and then transfer the patterns to the product by temperature and pressure. This special paper in the heat transfer process is called heat transfer paper.
Heat transfer paper is a printing material. When printing, the pattern is printed on the heat transfer paper and then transferred to the surface of the substrate by heat and pressure.
Wide application:
Heat transfer paper is mainly divided into sublimation paper and hot paper. Sublimation paper is mainly suitable for polyester fabrics, such as:
1. Clothing decoration cloth, curtain cloth, sand cloth, umbrella cloth, handbag, carpet cloth, toy cloth, etc.
2. PU or PVC surface, for example coated with PU or PVC fabric.
3. Front and back of various natural leathers. Thermal transfer paper is mainly used in hot paper for cotton, dark fabrics, etc.

Injection molding introduced by Plastic mold factory involves two basic steps:
Melt Generation by a rotating screw.
The propelling movement of the screw helps to fill the mold cavity with the molten resins which passes the injected resin under high pressure.
A hopper and runner system is used to place the raw plastic resins into a heating barrel carefully.
There’s a reciprocating screw inside the barrel which creates heat with a frictional force with heater bands. The plastic melts there.
As the machine is still moving (with the help of the screw), the plastic is then injected through a nozzle from where it gets inside a mold cavity through a gate system. It almost looks like a tunnel.
Finally, we get the desired shape of the plastic resins, which cools as it is inside the cavity.
While the plastic is inside the cavity, the machine applies a holding pressure. If you... less

They may also appear as ring-shaped bands on a product’s surface near the entry points of the Mold parts, or “gates”, which the molten material flows through. Flow marks won’t typically impact the integrity of the component. But they can be unsightly and may be unacceptable if found in certain consumer products, such as high-end sunglasses.
Causes and remedies for flow lines
Flow lines are most often the result of variations in the cooling speed of the material as it flows in different directions throughout the Mold parts. Differences in wall thickness can also cause the material to cool at different rates, leaving behind flow lines.injection molding defects For example, molten plastic, cools very quickly during the injection process and flow marks are evident when the injection speed is too slow. The plastic becomes partially solid and... less
