Lingtong is a professional engaged in the production of stainless steel curtain wall accessories, flat series, embedded board, angle code series, export series of products such as professional production and processing companies, have a complete and scientific quality management system.
The castings are first made of wax material and the model is welded to the gates with the same material. The modules are made (the castings can be individually set as a group) and dipped in refractory coatings (Water glass and fine sand mixture), and then sprinkled with refractory sand, (dip pulp, sanding several times, so that the sand layer is thick enough), until it is dry and cured, to the module heating, the wax from the pouring Mouth off, the formation of empty shell. Will be shells fired, so that a solid shell, the metal liquid poured from the gate, condensed, it becomes a metal castings, castings by shell shell sand, cutting, shot blasting, grinding, sorting, quality inspection Get the casting finished blank, for processing or other surface treatment and then processed according to the requirements.
Casting in general can be divided into pressure wax, shell, pouring, post-processing, testing
1, pressure wax, including (pressure wax, wax repair, group tree)
Pressure wax - the use of pressure wax machine for the production of wax die
Revised wax - the wax mold to be amended
Group tree --- the wax mold group tree
2, shells include (hanging sand, hanging pulp, air-dried)
3, pouring, including (roasting, chemical analysis, casting, shock shell, cut gate, grinding gate)
4, post-processing include (sandblasting, shot blasting, correction, acid)
5, including inspection (wax inspection, initial inspection, inspection, finished product inspection)
1. Casting size, high precision, good surface finish, can eliminate or reduce the mechanical processing, saving materials and processing costs.
2. Can produce complex parts of the shape, or a number of parts into one, eliminating the need for combination or welding work.
3. In the product can be cast on the beautiful text and patterns, enjoy your company and product image.
4. Materials are not restricted, according to customer needs to use the various national standard configuration of various alloy materials.
5. Casting production efficiency, good repeatability, easy to achieve mass production.
