Foreword: Since the establishment in 2009, we have been working with several food and beverage manufacturers in China all the time. Besides the moulds and plastic containers, we are also well versed in the packaging production line and relevant equipment. We have ever provided consultations and proposed cost-effective schemes for several production projects of dairy giants like Yili Group, Mengniu Dairy, etc.. Based in China, we are familiar with the packaging machinery manufacturers in the industry and the quality of their products. We can source and supply the packaging machinery to you, and ensure good quality and price. Liquid Nitrogen Filling Device Technical Specification Note: the store tank is optional. 1, the Equipment Description This model of machine is a ultra-efficient liquid nitrogen filling system which can be used in low-speed to high-speed production line. The system adopts the rocket insulation technology, combined with technologies from Germany and USA. The liquid nitrogen is precisely injected into each container, and then vaporize to produce internal pressure, thus meeting designed filling requirements. The liquid nitrogen is transported from the tank through the vacuum insulated tube to the filling tank. The liquid nitrogen is purified by gas-liquid separation procedure and then supplied to…

Introduction There are numerous mould manufacturers in the industry. At first sight, all the moulds looks similar. But actually there are many factors that will affect and determine the inside quality of mould. In this article, we’ll analyze these factors one by one. 1, Choice of Mould Steel Steel is the decisive factor that determines the quality of mould. Choosing the right steel is of utmost importance. The criteria of choosing are as follows: (1) Requirement of Molding Materials For different plastics, we need to use different steels. Properties to be considered include high polish, corrosion-resistance, etc; (2) Price Choice of steel should follow the principle of “just only enough”, not “the more expensive the better”. Considering the cost of mould, we should choose the steel which is in accordance with the mould service life, to avoid unnecessary waste; (3) Surface Treatment Surface treatment of mould is also very important. Nitridation can enhance the surface hardness of steel and thus increase the mould service life measurably. Electroplating can be used to modify the steel effectively. For some plastic parts that require the steel to be high-polish and corrosion-resistant, we can use electroplating to enhance the properties of the steel. 2,…
