Simis Launches Three Inner Core Solutions to Empower Silica Sol Lost Wax Investment Casting
2026-04-01
Inner core: ceramic core, urea core, water soluble wax core
Recently, Simis Manufacturer has officially launched three built-in inner core solutions for the Precision Casting market:ceramic core, urea core, and water soluble wax core. These solutions are fully compatible with Silica Sol Investment Casting technology, providing stable and reliable molding support for high-end precision castings with complex inner cavities, closed flow channels, and deep hole structures.
As a technical service provider specializing in silica sol Lost Wax Casting, Simis has long been engaged in the precision molding of stainless steel, alloy steel, superalloy and other materials. In response to the stringent requirements of the aerospace, automotive power, fluid valve, and medical device industries for refined, lightweight, and residue-free internal structures, the company has completed the iteration and upgrading of core materials and processes, establishing afull coverage capability for three types of inner cores.
Three Inner Core Solutions and Their Application Advantages
1. Ceramic Core
It features excellent high temperature resistance and dimensional stability, suitable for superalloy and ultra-complex thin-walled inner cavities (such as turbine blades and combustion chamber components). With high strength and minimal deformation, it achieves high-precision internal cavity molding and meets aviation-grade reliability requirements.
2. Urea Core
It has good water solubility, short preparation cycle and cost-effectiveness. It can be quickly dissolved and removed with hot water without strong corrosion processes, making it suitable for medium-complex inner cavity castings, balancing efficiency and economy for mass production.
3. Water Soluble Wax Core
It boasts a smooth surface, stable dimensions, environmental friendliness and odorlessness. It is highly compatible with silica sol shells, dissolves completely without residue, and effectively protects precision shells. It is especially ideal for valve bodies, pump bodies and hydraulic components with high requirements for inner cavity smoothness and environmental protection.
Technical Value and Industrial Significance
The large-scale application of the three inner core solutions marks a key breakthrough for Simis in the field of precision casting of complex inner cavities:
- Solves industry pain points such as demolding/sand cleaning difficulties for closed cavities, cross holes and deep cavities
- Reduces secondary machining, improves yield and delivery efficiency
- Primarily uses hot water dissolution, reduces acid and alkali usage, and is greener and safer
- Highly compatible with silica sol processes, ensuring casting dimensional accuracy and surface quality
Simis will continue to focus on material innovation and process optimization, providing global customers with one-stop precision manufacturing services from design, core making and casting to finishing. We are committed to empowering high-end equipment manufacturing with more efficient, precise and environmentally friendly production upgrades.
