hallmarking Setup
industrial hot plate
The hot plate features a durable steel construction, capable of reaching temperatures up to 350°C. It is equipped with an energy regulator and a thermostatic or digital controller, tailored to meet the specific requirements of the customer. This design ensures precise temperature control and consistent performance for various industrial applications.
table drilling machine
table drill machine is an essential tool in the hallmarking process for its precision in drilling metal samples, creating mounting holes, and preparing test pieces, all of which contribute to accurate and reliable hallmarking.
assaying scale weights
Assaying scale weights are precision weights used in the assaying process to determine the purity and composition of precious metals. They are calibrated and certified weights that help ensure accuracy and consistency in measuring and testing metal samples.
annealing furnace
The updated EDR furnace features silicon carbide rod heating elements with a maximum output of 2.5 kW per zone and electronic power control, enhancing the lifespan of the elements. It boasts a stainless steel structure with insulated walls and a cooling system with three fans, maintaining an external temperature between 50-90°C. The new design includes a larger muffle that accommodates up to 7 cupels per row in the standard model and up to 10 cupels per row in the EDR/10 model.
rolling press
olling press is a crucial tool in the hallmarking process, used for preparing metal samples by adjusting thickness, ensuring surface smoothness, and creating consistent test pieces necessary for accurate purity testing and certification.
fume hood and srubber
fume hood and scrubber are essential for maintaining a safe and environmentally friendly working environment in the hallmarking process, handling hazardous fumes, and ensuring compliance with safety and environmental regulations.
hallmarking instrument
the kit typically includes a set of acids with different concentrations and a testing stone or surface where the gold sample is placed. The principle behind the test is based on the chemical reaction between gold and the acids.
