In our foundry, the Investment casting process is operated with the most advanced technology in China. In the whole process, all-metal alloys are available, we can customize investment castings according to your material specifications. Even material compositions are feasible for production. To ensure the best quality, quality control will be done in each investment casting process.<\/p>\n<h3><span id=\"Here_are_the_whole_steps_of_the_investment_casting_process_in_our_foundry\"><strong><b>Here are the whole steps of the investment casting process in our foundry:<\/b><\/strong><\/span><\/h3>\n<p><strong><b>Step 1: Tooling Making<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6700\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/mould-300x225.png\" alt=\"mould\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/mould-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/mould.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Tooling Making is the first step for investment castings. That is the basis to achieve precision products. Such tooling or pattern will be precision machined by our CNC center. Regularly speaking, the tooling cost will be charged from our customers for the sample order of a new product is placed. But it is just a one-off payment. We will not ask for this fee from second orders.<\/p>\n<p><strong><b>Step 2: Wax Injection and Pattern Assembly<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6701\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-2-300x225.png\" alt=\"shell\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-2-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-2-768x576.png 768w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-2.png 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>After the casting patterns are finished, we will make the wax pattern. The wax pattern is obtained by injecting wax into the pattern. We will get a model with the same dimensions as desired products. Then, we will repeat the injection job for more wax patterns. Then assemble these wax patterns onto the sprue. Finally, hang these pattern assemblies at room temperature for drying.<\/p>\n<p><strong><b>Step 3:Shell Coating<\/b><\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>In Shell coating, the pattern assembly will be dipped into a ceramic slurry and coated with a refractory material. Repeating this process several times until getting a certain thickness and strength. Then, the ceramic shell is finished and then put into an atmospherically controlled environment until be dried.<\/p>\n<p><strong><b>Step 4: Dewax<\/b><\/strong><\/p>\n<p>Putting the shell in a steam auto calve and rapidly heated. So that the wax will melt and run out through the gate and pour up under high temperature. The ceramic shell molds must be fired to burn out the last traces of pattern material and to preheat the mold in preparation for casting. Usually in the range of 1600-2000 degrees Fahrenheit. That is why investment casting is also called \u201clost wax casting\u201d.<\/p>\n<p><strong><b>Step 5:Casting or Pouring<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6702\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-1-300x225.png\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-1-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/shell-1.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>After dewaxing, we will melt the steel or aluminum ingots into liquid status. Then pour the liquid metal into the spruce. Then cool it under room temperature for a moment. Casting is the key step in the whole investment casting process.<\/p>\n<p><strong><b>Step 6: Shell Removing<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6703\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-3-300x225.png\" alt=\"shell removing\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-3-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-3.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>After Cooling, Break the ceramic shell and cut the individual investment castings from the sprue. Then remove the excess metal from the casting body by grinding.<\/p>\n<p><strong><b>Step 7:Heat Treatment<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6704\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-1-300x225.png\" alt=\"heat treatment\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-1-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-1.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>The heat treatment is usually done after finishing castings. The process can improve the mechanical properties of casting blanks. The main heat treatment processes are Normalizing, tempering, annealing, hardening, and tempering, and carburizing. On the cost, heat treatment is additional. If you have heat treatment requirements, it will be cleared in advance and extra cost counted.<\/p>\n<p><strong><b>Step 8: Shot Blasting\/Sand Blasting<\/b><\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6705 size-medium\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-2-300x186.png\" alt=\"Investment Casting Process\" width=\"300\" height=\"186\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-2-300x186.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/investment-casting-China-2.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>To remove scales and achieve a better surface finish, investment castings will be shot blasted or sandblasted by small steel balls. So all the foundries must be equipped with shot blasting machines.<\/p>\n<p><strong><b>9. Anti-rust Oil Painting &amp; Surface Treatments<\/b><\/strong><\/p>\n<p>To avoid rusting, castings will be dipped into anti-rust water or oil. The other surface treatments can also be performed in this step like paint spraying and galvanizing.<\/p>\n<ol start=\"10\">\n<li><strong><b> Quality Inspection<\/b><\/strong><\/li>\n<\/ol>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-6706\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2022\/04\/casting-inspection-300x225.png\" alt=\"casting inspection\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/casting-inspection-300x225.png 300w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2022\/04\/casting-inspection.png 600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>Inspection is also a step for investment castings quality control.
