Having an understanding of plastic injection mold design basics can help you avoid part defects, such as mold warpage and gas trap (formerly known as mold burns), voids, short shots and various other incorrect design flaws, which can result in expensive & time-consuming product callbacks and part rework.
Below is a plastic mold design checklist to cover with your plastic injection molder.
Resin Requirements
The first thing to know when seeking out plastic injection mold design assistance is what type of resin your application requires – commodity or engineering grade. The type of resin you require is based on numerous factors – from part environmental conditions to load bearing.
Remember, there are over 30,000 resin formulas available so it’s important to know your environmental requirements so you can... less

The weight capacity is the amount of weight that the tool can lift without any problems. Our hydraulic vehicle positioning jacks come in different weight capacities and are usually marked in tons. You should use a jack that corresponds to the weight of the vehicle. Remember that the bottle jack supports only 60% per cent of vehicle weight. That means that a 2-ton bottle jack can lift a 3-ton car.
Lifting Range
Next thing to think about is the lifting range of the bottle jack. It is essential to check how high the bottle jack can lift corresponds to your needs. Commonly, bottle jacks lifting range varies from 9 to 18 inches.
Material and Quality
Another critical factor is the material used in making the bottle jack. Both the body and the base of bottle jack should be made from durable and sturdy materials. The bottle jack should be able to withstand the pressure from lifting and holding heavy vehicles. A good quality bottle jack is made of a combination of iron and alloy steel of... 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

These fittings aren’t normally used in new constructions but renovation projects. The pp compression fitting are ingenious because you can use them in places where welding isn’t an option. Also, compression fittings can be used on leaky pipes such as broken water lines in an emergency situation.
Step 1: A PP COMPRESSION FITTING
Alright, these fittings are composed of 3 parts, the valve in this case, a sleeve and a retainer nut. All of these work together to make a solid leak free connection.
Step 2: TOOLS/MATERIALS FOR THE JOB
You’ll be needing some tools and materials to install these the correct way, starting with either 2 open end wrenches the size of the retainer nuts or 2 adjustable wrenches, and I always like to install a bit of pipe dope to lubricate and seal my connections, so I’ll be using my trusty can of pipe dope.
Step 3: PREPPING THE PIPE/FITTING
So the first thing to do is to ensure that you... less

And that's not always because parents save money on their kids' shoes and buy inexpensive items, but also because kids grow really fast and what fits perfect this season can easily be outgrown the next. And the thing is, you can't really do anything about it until your little one's feet stop growing.
This article on foot growth in children is a good place to look if you're looking for this piece of information. According to experts, by the age of 10, most of the kids complete the feet growth process by 80 percent (for boys) or 90 percent (for girls). However, the full process stops around the age of 14 (girls) or 16 (boys).
That means that you'll be buying new pairs of boots for your kid every season until he or she reaches the age of 10. After 10 years old, you'll probably need to buy shoes every other year. And this is the optimistic scenario. Keep in mind that kids are energetic and... less

Let the heat transfer label manufacturers talks about it for you.
1. If you find that the tacky sublimation paper is damp, it is best to use a hair dryer or blow it in a ventilated place to let the tacky sublimation paper dry.
2. Try not to expose it to the sun, as this will cause deformation of the tacky sublimation paper, and will also cause the tacky sublimation paper to jam during use.
3. In the face of places where the phenomenon of returning to the sky often occurs, try to choose a better quality, and its moisture resistance will be better.
4. Try to put the tacky sublimation paper in a dry environment. Don't put too much tacky sublimation paper on the carton at one time.

In 1847, the first condensation polymers were produced. John Wesley Hyatt’s introduction of the plastic derivative Celluloid reinvented the global manufacturing market. Hyatt, together with his brother, would later go on to construct the crude yet innovative prototype for the first ever injection molding machine in 1897.
Early in the 20th century, the invention of Bakelite gave rise to the everyday usage factor of plastics. Leading to the 1930s, the invention of major vinyl thermoplastics such as PVC and Polystyrene makes its way to becoming household essentials, even in the current day. With the rampages of World War II going on, the world’s industry sectors needed to call for cheaper means of mass production; leading to the breakout wonders of Nylon in 1941. From 1945 to the mid-50s saw the transition of Polyethylene to Polycarbonate. And the widespread use of injection molding methods in... less

Taking a material like organic cotton and blending it with recycled polyester results in a garment with higher durability, more crease resistance, better drape, and faster drying time. The two fibers also absorb dye differently, resulting in the iconic “heather” look we love!
2. Recycled Polyester Fabric: it gives plastic a second life
Around the world, 1 million plastic bottles are bought every minute. While most bottles go straight to a landfill, it’s possible to recycle them into textiles and other products. Demand for polyester fabrics made from recycled plastic creates a market for recycled bottles, which helps save more of them from a fate of 400+ years decomposing in a landfill.
3. Recycled Polyester Fabric: it’s a smart alternative to new poly
Recycling “waste” plastics (rather than drawing on more natural petroleum) saves 75% of the energy, 40% of the CO2, and 90% of the water required for production. And... less
