In the traditional foundry industry, sand mold making has always been a key link affecting productivity, cost and molding capability of complex structure castings. With the increasing market demand for high-precision, short-delivery and complex structure castings, the traditional manual molding and mold manufacturing methods have been difficult to meet modern manufacturing requirements. Sand 3D printers, as an advanced additive manufacturing technology, can directly print complex sand molds and cores without the need for molds, dramatically shortening the production cycle, reducing costs, and enhancing design freedom. In this article, we will discuss why traditional foundries should consider introducing sand 3D printing technology to enhance competitiveness, optimize production processes, and meet market demand for efficient and accurate casting. The following is written exclusively for foundry owners, and we hope it will inspire you.<\/p>\n\n\n\n
--Customers want to do small quantities of trial parts, do a metal mold to 200,000, the result of the order is only 50 pieces, a calculation found that the mold cost more than the money earned, can only give up the order!
--The customer had an order for an aerospace part with honeycomb structure, and the traditional sand core assembly error was bigger than the part size, so it was a big headache to stare at the scrapped casting!
--Competitors with 3D printing took a well-known automotive battery pack orders, their own offer is lower than others 30% or did not win the bid, and finally inquired about the delivery of people faster than us 2 months, very helpless!<\/p>\n\n\n\n
--Customers do not move to change the design of the warehouse piled up more than 300 sets of scrap molds, checking the accounts found that the mold inventory occupied half a year of profit, which is too painful to taste!<\/p>\n\n\n\n
--Customers sent a complex structure of the pieces over, and said that the price is not a problem, an assessment found that the traditional casting process can not be done, looking at such a high value-added orders can only be given up!<\/p>\n\n\n\n
Below we help all bosses one by one to sort out clearly, an article to let you fully understand the 3D printing sand casting technology!<\/strong><\/p>\n\n\n\n Sand 3D printing is a relatively new technology, simply put, is like building blocks, with special materials layer by layer \"pile\" out of the casting sand.<\/p>\n\n\n\n In the past, the traditional method of making sand molds may need to make molds first, and then use the molds to shape, the process is more complicated, and if you want to make some sand molds with very strange and complex shapes, it will be particularly difficult and costly. But sand 3D printing is different, it works with a 3D model in your computer. You input the data of the 3D model of the designed casting into the 3D printer, and the printer will, according to the shape and structure of the model, put special sand or sand-like materials, according to the layer by layer in a precise way and bonded up, just like using countless thin \"sand pieces\" gradually built into a complete sand mold. In this way, no matter how complex the shape, as long as it can be designed in the computer, it can be printed out, and the speed is quite fast, and do not need to make complex molds like the traditional method, can save a lot of time and cost it.<\/p>\n\n\n\n Sand 3D printing is usually done usingBinder Jetting (BJ)<\/strong>The basic principle is as follows:<\/p>\n\n\n\n The existence or birth of each technology must have its \"mission\". Commonly known as a solution to a particular problem, to meet market demand, this is the value of its existence. Below we take a look at the sand 3D printing technology to solve the thorny problems encountered in the traditional casting, as follows:<\/p>\n\n\n\n The price of a sand 3D printer is not cheap (usually the larger the size the more expensive), to buy is relatively cautious, especially small and medium-sized foundries. In order to help bosses to assess whether there is a need to buy, we have specially organized the following some evaluation points, to give the boss of the traditional foundry a reference, and then according to their own situation to decide whether to buy:<\/p>\n\n\n\nWhat is sand 3D printing?<\/h2>\n\n\n\n
