Low Ash Precision Investment Casting Wax for Noble Metal Lost Wax Patterns
Low Ash Precision Investment Casting Wax is a low‑ash pattern wax formulated for noble metal lost‑wax casting. The wax can be injected to form intricate wax patterns for jewellery parts. During high‑temperature dewaxing and burnout process, it decomposes thoroughly with minimal residual ash, avoiding inclusions and surface defects on finished precious‑metal castings in precision jewellery foundries.
Product Overview Low Ash Precision Investment Casting Wax is specialized injection‑type pattern wax developed for noble‑metal lost‑wax investment casting. Under appropriate heating condition, the wax possesses favourable fluidity for injection moulding to reproduce fine and complex details of jewellery wax patterns. When subjected to the burnout cycle inside the casting furnace, the wax decomposes and volatilizes almost completely. Extremely low residual ash prevents slag inclusions, pits and blemishes on gold, silver and platinum cast parts. This pattern wax satisfies strict quality requirements for fine jewellery, ornaments and small‑sized precious‑metal precision components in professional jewellery casting workshops.
Key Features ‑ Extremely low‑ash formulation to minimize casting defects after thermal burnout ‑ Good injection fluidity for replicating delicate, intricate jewellery pattern details ‑ Appropriate hardness and dimensional stability to reduce deformation of wax patterns ‑ Controlled thermal shrinkage for consistent dimensional accuracy of final cast parts ‑ Clean burnout performance adapted for gold, silver and platinum noble‑metal casting
Typical Technical Properties ‑ Chemical Type: Modified synthetic investment casting pattern wax ‑ Appearance: Pale beige hard pastilles or wax ingots ‑ Melting Range: Refer to TDS ‑ Ash Content: Refer to TDS ‑ Linear Shrinkage: Refer to TDS
Applications ‑ Jewellery foundry: Injection wax patterns for gold, silver and platinum jewelry casting ‑ Precious‑metal ornament production: Lost‑wax pattern material for delicate decorative pieces ‑ Precision noble‑metal component workshop: Pattern wax for small‑size high‑detail cast parts ‑ Casting material supplier: Raw pattern wax for jewellery investment‑casting manufacturing
Processing Recommendation Adjust wax injection temperature and injection pressure according to mould structure to obtain complete wax patterns. Inspect wax patterns for deformation or surface flaws before investing. Perform burnout curve verification in the furnace prior to formal mass casting production.
Storage & Handling Store in cool, dry warehouse away from heat sources. Reseal packaging after opening. Wear protective gloves during handling solid casting wax.
