1. Pretreatment of materials In the mixing of money, proper pretreatment of the components in the formula can effectively improve the mixing uniformity. Surface treatment of additives: Mainly used for inorganic additives, because the compatibility between inorganic additives and organic resins is not good.The additive is subjected to hydrophobic treatment […]

Color Masterbatch Formulation Research Posted by Andy When you get an order from your customer for a new color masterbatch, if you have no experience, you need to research the approx. formulation first. So actually, the most important thing is you have a good color blending engineer. Now we example […]
The screw of the twin-screw extruder is a modular combination. The combination of the entire screw should be selected according to the specific formulation, material characteristics, mixing requirements, and operating conditions. The following example illustrates how to make a screw (barrel) component combination for different usage requirements. First, make sure […]
There are two main treatment methods for twin-screw extruders during emergency stop: normal parking and emergency parking. The main steps are as follows: Normal stop. When the extruder is nomal stop, it can be stopped in the following steps: 1.Adjust the feeder speed to zero and press the stop switch […]
PA Engineering plastic is used in automotive parts and interiors widely. Common fillers for engineering plastics: mica, talc, wollastonite, glass beads, rare earths and alkali metals When 20% of mica is added to PA6, the tensile strength is increased by 20%, and the bending strength and heat distortion temperature are […]
1. The machine does not allow empty to run, so as to avoid the screw and barrel rolling. 2. Change the gear oil regularly. The first oil change time is 3 months after the machine is running. The second oil change time is 6 months after the first oil change […]
The Cleaning of Twin Screw Extruder Posted by Andy When do you need to clean your extruder? Some plastic will be carbonization after the extruder long time continues working. It will have some black spot inside the final granules. Some materials remain on the screw or barrel and gelled, and the material […]
