Tensile testing machine test speed
At present, some domestic equipment in 50 ~ 500 mm / min, some in 0.001 ~ 500 mm / min, the former generally use ordinary trapezoidal screw plus speed motor or frequency conversion speed control system, the cost is lower, wear and tear. Over time, the test more will produce a shaking of the center link plate, affecting the test accuracy, and time soon, the machine is noisy and easy to break; a laboratory put such a tractor-like tension machine, certainly not in a good mood, the follow-up maintenance is also a lot of overhead. So we must also think about our testers. The latter uses a servo system with ball screw, high precision, constant speed and stable speed, small wear and tear, better durability. The measured test repeatability is also good. The standards have specified test conditions, what material how much speed, because the speed is not the same measured force value is not the same. Such as all kinds of production equipment robots are used in the servo system, if you have the opportunity to go to the car factory to see, car parts in each position is no difference. Think about how relieved you can be to put such a machine into your own factory, out of the product after the test, the heart will be confident, the price will be sold accordingly, the customer is also easy to accept.
As flexible packaging materials are mainly polymer or its related materials, as mentioned before polymer materials elongation is far better than metal, fiber, wood, plate and other materials, so the detection of polymer tensile strength machine with the usual material tensile properties testing tensile strength machine has some differences, especially need to pay attention to the effective stroke of the electronic tensile strength machine and the specimen fixture two aspects. Tensile properties of plastics and rubber is one of the most important and basic mechanical properties, which largely determines the use of the plastic and rubber occasi
