Background of handheld XRF analyzers

XRF (X-ray fluorescence) is an innovative, non-destructive technology for material analysis. It`s unique and almost universal,
An X-ray gun sees sample contents by using an X-ray source to measure the secondary ways (fluorescent) the sample emits. Such an analysis is clear and fast.

Portable XRF Spectrometers can be used in any field that requires analysis of elements or compounds from Na to U. The main business industries include building materials (cement, glass, ceramics), metallurgy (steel, non-ferrous metals), petroleum (trace elements such as S, Pb, etc.), chemical industry, environmental protection, food safety, geological mining, commodity inspection, quality inspection, and human body trace element inspection, etc.

handheld XRF metal tester Working principle

The sample is bombarded with X-rays, and the sample is excited to produce X-ray fluorescence.

X-rays usually knock out the inner electrons of the K and L layers of the element atoms, and the generated holes are filled by the high-energy outer electrons. High-energy electrons replenished to low-energy orbits radiate the excess energy as X-ray fluorescence.

These radiated spectral lines contain the characteristics of various elements. Like a fingerprint, and independent of the chemical valence states of the atoms. The intensity of the radiation is proportional to the concentration of this element in the sample.

✔ Wide Applicability: Our blister cards are suitable for various precious metal products, including gold bars, silver coins, earrings, necklaces, and more, providing a secure and premium presentation.

Q3: Do I need custom molds to use the blister packaging machine?

A: Yes, custom molds are required for our blister packaging process. There are two main types:

Blister Mold (Aluminum Mold): This is mounted on the machine and must be precision-engineered to match the exact dimensions of each specific gold/silver bar or coin. Therefore, each unique product size requires its own dedicated aluminum mold.

Card Die-Cutting Mold (Steel Rule Die): This is used to punch the printed card into its final shape. Typically, one card size requires one die.

Cost-Saving Tip: Multi-Cavity Molds. To help reduce your initial mold investment, we offer mold combination services. You can combine 2 or 4 different product card designs into a single die-cutting mold. Subsequent orders for these combined products must be produced in equal quantities. Our team can advise on which sizes can be efficiently combined based on your needs.

Q4: What is the working principle and operation process of the blister packaging machine?

A: Our machines use a reliable and precise method for secure sealing.

*Operation Process:

2-Station: An operator manually rotates the turntable to position the mold under the sealing head. A sensor triggers the automatic descent of the head for pressing. Meanwhile, the operator can load the next product at the opposite station. Once sealing is complete, the head retracts, and the operator rotates the turntable to remove the finished package.

4-Station: The process is similar but more automated. After sealing, a robotic arm automatically picks and places the finished package onto a conveyor or collection tray, significantly boosting efficiency.

*Working Principle: The machine utilizes High-Frequency (HF) energy to create an instant, penetrating heat seal. This method ensures a strong, permanent bond without burning or damaging the delicate surface of your precious metal products. It employs a direct pneumatic pressing system for uniform pressure distribution across the entire seal area. The system is equipped with an anti-arcing (spark suppression) protection circuit, which safeguards both the expensive HF molds and your valuable products.

Q5: Do you offer free samples of the custom blister cards?

A: We do not offer free samples for custom-designed blister cards. Each custom design requires the creation of unique printing plates and setup, which incurs specific production costs. However, we are pleased to provide a free Standard Sample Kit at no charge. This kit contains physical samples of various standard materials and printing techniques, allowing you to evaluate our print quality, material feel, and functional capabilities to inform your design process.

Q6: Are your blister packaging machines suitable for all sizes of gold/silver bars and coins?

A: The suitability for blister packaging is primarily determined by a product’s physical dimensions (Length, Width, Thickness) rather than its weight alone. As long as the product’s size can be accommodated within the machine’s mold and platen area, it can be packaged. Even items with a high gram weight are perfectly suitable if their physical dimensions fall within the machine’s design limits. Our solutions are versatile and can be adapted for a wide range of precious metal items, from large bars to delicate coins and jewelry like earrings and necklaces.

Product Details

[Graphite  Mold]

Graphite mold is a molding tool made of graphite material. With the characteristics of graphite such as high temperature resistance, fast thermal conductivity and high chemical stability, it is widely used in metal(Gold,Silver,Copper.etc.) casting, semiconductor processing, glass molding, powder metallurgy and other fields. The following is a detailed analysis of graphite mold:

1. Core Characteristics 

High temperature resistance:The melting point of graphite is as high as 3650°C, and it can work below 1600°C for a long time. It is suitable for casting high-temperature molten metals (such as gold, silver, copper, and aluminum).

High thermal conductivity:The thermal conductivity is 2 to 5 times that of steel, which can quickly transfer heat, shorten the cooling time of metal, and improve production efficiency.

Low thermal expansion coefficient:The dimensional stability is good at high temperature, the mold is not easy to deform, and the molding accuracy is guaranteed (±0.05mm).

Self-lubricating property:The graphite layered structure can reduce friction with the metal liquid, demolding is smooth, and the risk of sticking is reduced.

Chemical inertness:Acid and alkali corrosion resistance, does not react with most molten metals, and avoids contamination of metal purity.

2.Application.

Precious metal casting:Jewelry: Used for lost wax casting or direct casting of gold and silver, making rings, pendants, etc. with complex patterns, with high surface finish.
Investment gold bars/coins: Casting standardized gold bars and silver coins to ensure consistent weight and shape.

Semiconductor industry:Crucibles for growing single crystal silicon and polycrystalline silicon, as well as graphite boats and fixtures in wafer processing.

Glass industry:Pressure molding molds for optical glass and bottle glass, resistant to high temperatures and non-sticky to molten glass.

Powder metallurgy:Sintering molds for cemented carbide and diamond tools, withstand high pressure and high temperature environments.

Continuous casting:Continuous casting crystallizers for metals such as copper and aluminum to improve the surface quality of the ingot.

3. Processing and selection

Material grade:Isostatic graphite: high density (≥1.8g/cm³), high strength, suitable for precision casting.

Molded graphite: low cost, used in general industrial scenarios.

Anti-oxidation coated graphite: SiC or ceramic layer coated on the surface to extend the life of the mold.

Processing technology:CNC precision engraving: to achieve complex cavity structure, the accuracy can reach 0.01mm.

Surface polishing: Ra≤0.4μm, reduce the flow resistance of molten metal.

Key parameters for selection:Density (determines wear resistance) | Particle size (affects surface roughness) | Flexural strength (≥30MPa) | Anti-oxidation temperature (whether coating is required).

4. Feature

High temperature resistance, good thermal stability, high brittleness, poor impact resistance
Fast thermal conductivity, high production efficiency, easy to oxidize in high humidity environment
Excellent demoulding performance, high precision processing cost
Reusable (life 50-200 times)

5. Precautions for use and maintenance

Preheating treatment:Before the first use, it is necessary to slowly heat up to the working temperature (such as 200°C/h) to avoid thermal stress cracking.

Mold release agent selection:Coat boron nitride or graphite emulsion to further reduce metal adhesion.

Cleaning and maintenance:Clean up residual metal slag after use (can be cleaned by ultrasonic cleaning or high-pressure gas blowing).

Store in a dry environment to prevent moisture absorption and oxidation.

Prolong Life:Regularly check the surface cracks or wear of the mold and replace it in time to avoid affecting product quality.
