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 guids

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...

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...
