How to select injection molding screw
Plastic injection machine screw and barrel has the function of conveying,melting,mixing,compression,measurement and exhaust,which playing an important role in plasticizing quality. Screw and barrel is the main core unit of the plastic injection molding machine,such as the heart of the human, which can directly reflect the performance of the machine.So how to choose a good screw and barrel is the p...
How to improve the performance of cheap linear guides
Linear guides from RobotDigg The RobotDigg linear guide rails, despite also coming from China, are in my experience of better quality than the cheapest Chinese guides. Both the machining and the materials used are of higher quality. They cost a bit more than the cheap Chinese ones, but nothing extravagant. Out of all options this one seemed like the best value to me, so I used their 440C SUS MGN9 ...
Plastic Injection Molding Machines
When it comes to plastics processing tools, plastic injection molding machines are without a doubt one of the most versatile pieces of equipment. These machines can be used to make virtually anything, ranging from mini hearing aid parts to large individual parts like tractor hoods.The so-called plastic injection moulding process refers to: the plastic material in the barrel of an injection molding...
Technology used in smart-farm industry
The current state of global food production is so full of contradictions. We produce more than enough food for every person on earth, yet hundreds of millions go hungry each day.Also cultivating the food we need to survive is a damaging process, with emissions and pollutants from agriculture threatening both the environment and human health. Recognizing a necessity for more sustainable and efficie...

International Space Station Crew 3D-Prints Meat In Space For The First Time!
For the first time in the history of space, meat was ‘created’ on the International Space Station (ISS) and no animals were harmed in the making of this 3D bio-printed ‘space beef.' On October 7, Aleph Farms, an Israeli food company, announced that its experiment aboard the space lab resulted in the first lab-grown meat in space. Albeit climate change was the main motivation for the company to pro...
3D printer filament extruder and production line
Since the drop in the price, 3D printers become popular to be used. However,once you are a owner of a 3D printer you will soon realize that your wallet is become more and more thin. Yes,you need plastic filament to print what you want. But the price for these filaments tend to top the actual material costs, this will become a big problem to the development of the growing 3D printer. Recently, we r...
Recyclable Items - Recycling
What is recyclable? Recyclable definition, to treat or process (used or waste materials) so as to make suitable for reuse: recycling paper to save trees, recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution (from landfilling). All plastics #1-7 (excep...
Reflow or Wave Soldering Ventilation
Soldering Ventilation Either reflow soldering or wave soldering for batch production we need to consider of the soldering ventilation indeed. Questions: "(a) The fume from the reflow or wave soldering machine is leaking to the surrounding although it is enclosed and attached to the local exhaust ventilation system with a capacity of 5000 CFM. (b) Current local exhaust ventilation system or the por...
Stepper driver for 3D Printer?
Stepper Driver I've heard there is accident that user do Not apply a stepper driver to make the stepper motor work, but connect the stepper motor to power supply directly, the result is the stepper burn stupidly. It's Not a joke. Let's check out the stepper driver series that companies has bring us. A4982, A4988, DRV8825 (Texas Instruments) , TMC2100, TMC2130, TMC2208, TB6560, TB6600 and other ste...
