Focusing on special parts
Sand casting is one of the oldest and most versatile metal casting processes, dating back thousands of years. This method involves creating a mold from a sand mixture and pouring molten metal into the cavity to form the desired shape. Known for its ability to produce large and complex metal parts with excellent mechanical properties, sand casting machining is widely used in industries such as automotive, aerospace, construction, and heavy machinery. Its cost-effectiveness, scalability, and adaptability to a wide range of metals make sand casting an indispensable technique in modern manufacturing. Explore how automated precision sand casting can meet your production needs with efficiency and precision. BulkTEK excels in precision sand casting, setting the standard among sand casting companies.

Automated sand casting lines, including DISA MATCH 130 and Hunter HMP-20.
Metals (iron, aluminum, bronze).
Max casting size: 1000mm x 1000mm x 500mm. Tolerances: ±0.5mm.
Quality Management System: ISO 9001:2015 certified, ensuring consistent casting quality.
Inspection Equipment: Spectrometers, CMM, and hardness testers.
Quality Assurance Process: Material verification, mold inspection, and final casting inspection using spectrometers and CMM to ensure material composition and dimensional accuracy.
Pattern Creation:
A pattern, typically made of wood, metal, or plastic, is created to form the shape of the final part.
Mold Making:
The pattern is placed in a sand-filled mold box, and sand is packed around it to create the mold cavity.
Core Making:
Cores are used to create internal cavities or complex geometries within the cast part.
Melting and Pouring:
Metal is melted in a furnace and then poured into the mold cavity.
Cooling and Solidification:
The molten metal cools and solidifies within the mold.
Shakeout and Cleaning:
The sand mold is broken away, and the cast part is cleaned and finished.
