Fluorine-lined centrifugal pumps are mainly used to transport corrosive chemical media. Since the corrosion-resistant fluoropolymer lining (PTFE or FEP) is applied to the inner wall of the pump and key flow parts (impeller, housing, etc.) through high-temperature sintering, a dense protective layer is formed, which completely isolates the contact between the medium and the metal. This enables the fluorine-lined centrifugal pump to resist the erosion of a variety of chemical substances, making it the "industry darling" for corrosive fluid transportation.

Walking into a plastic recycling plant in the suburbs of Bangkok, the plant manager Anan pointed to the newly installed high-speed optical sorter for plastic materials and said frankly: "This machine turned our monthly loss into profit." Today, when the global recycling gross profit is less than 8%, this technology is becoming the key to the survival of the industry.

Pain point analysis: The hidden cost of manual sorting

"Green Source Recycling" in Haiphong City, Vietnam, once conducted an experiment:

20 workers sorted mixed plastic bottles for 8 hours, with an error rate of 13%

Mistakenly judged black PET bottles were mixed into the HDPE pile, and the entire batch of materials depreciated by 40%

Night shift efficiency plummeted by 35%, but the work injury rate increased by 22%

Until they introduced efficient plastic pellet sorting equipment, the sorting accuracy jumped from 87% to 99.2%. In just three months, the material loss cost was reduced by US$110,000.

Technical analysis: Black technology that does not rely on color to identify materials

The core of the new generation of advanced technology for plastic waste sorting is:

Molecular-level detection: Near-infrared spectroscopy identifies polymer molecular structures, and can even identify agricultural films that have been degraded for three years

Dual-precision spray valve: 256 air bullets are fired in 0.03 seconds to accurately remove 0.5mm PS impurities

Self-learning algorithm: After a machine in a Mexican factory ran for half a year, the recognition rate of faded LDPE increased to 98.7%

Cost comparison: How automation rewrites the profit formula

Take a medium-sized factory with a processing capacity of 50 tons/day as an example:

Data source: 2024 Global Recycling Equipment White Paper

The actual case of Indonesia's "Ocean Regeneration" company is even more amazing: 9 months after installing the sorting machine, they actually grabbed a long-term order from Japan's Toyobo at a price as low as $15 per ton - just because the purity reached the standard of 99.3%.

In the field of industrial sorting, high-precision CCD color sorters and industrial-grade NIR sorting systems are often compared. As a brand that has been deeply engaged in color sorting technology for 20 years, HTsorter combines industry practice with cutting-edge technology to analyze the core differences and application scenarios of the two for you.

1.Detection principle: color recognition vs. molecular analysis

CCD color sorters are based on visible light imaging technology and capture the surface color and shape characteristics of objects through red, green and blue primary color sensors. For example, Japan's Satake's Evo RGB model uses a full-color CCD camera that can identify tiny color differences of 0.16×0.2mm and accurately sort surface defects of almonds, coffee beans and other particles.

NIR (near-infrared) sorters detect the chemical composition of materials through the interaction of infrared light with the molecular vibration characteristics of substances. For example, the SSM color sorter can be equipped with a high-performance InGaAs sensor, which can accurately remove plastics and glass through molecular differences even if the color is the same as the raw material.

Applicable scenarios:

CCD is more suitable for high-precision color sorting (such as sorting mixed-color particles in PET fragments);

NIR is good at handling foreign objects with similar colors but different materials (such as pesticide residues or plastic fragments in food).

2. Comparison of technical advantages

Typical cases:

HTsorter CCD models can achieve 99.9% blue and green bottle cap sorting accuracy in plastic recycling;

HTsorter NIR system is used for nut processing, which can remove moldy particles at high speed without affecting the production line speed.

3. Collaborative application and maintenance points

Complementary scenarios: Some high-end models (such as SSM color sorters) are equipped with CCD and NIR dual sensors at the same time. CCD is used to remove color abnormal particles first, and NIR is used to remove material foreign matter, achieving "double insurance".

Maintenance differences:

CCD requires regular lens cleaning and color calibration (such as the automatic sensitivity setting function of Evo RGB);

NIR system pays more attention to light source stability, but almost no contact debugging is required.

HTsorter's solution

For different industry needs, we provide:

Customized CCD sorting solution: suitable for color-sensitive fields such as food and jewelry;

Industrial-grade NIR system: designed for complex environments such as recycling and minerals, supporting batch removal of inorganic impurities;

Mixed sorting model: combining CCD+NIR technology to meet the dual needs of high-end customers for precision and efficiency.

An industry earthquake caused by a "leak"

In 2023, a well-known electric vehicle brand in Southeast Asian countries was forced to recall thousands of new cars due to the failure of the high-voltage DC relay seal - the reason was a micro-crack on the ceramic shell that was invisible to the naked eye. This lesson worth millions of dollars made the entire industry realize: "Invisible loopholes are the biggest risks."

As the new energy vehicle industry in Southeast Asian countries soars (Thailand aims to produce 725,000 electric vehicles in 2030), manufacturers of high-voltage DC relays are facing a dual challenge: not only to meet the stringent requirements of the 800V high-voltage platform, but also to control costs and seize the market. The airtightness of the ceramic shell, as the "armor" of the relay, directly determines the product life and safety.

1. Why do high-voltage DC relays have to "stick to" ceramic housings?

1. Survival rules in the high-voltage era

The 800V high-voltage platform has become the mainstream trend of electric vehicles, with larger currents and more intense heat generation. Traditional plastic housings are prone to deformation and aging, while ceramic housings have become rigid demands due to their high temperature resistance (>1000℃), strong insulation and long life.

But hidden dangers are hidden in the details: tiny pores or welding residues during the ceramic sintering process may cause hydrogen leakage, which may cause relay malfunction or battery thermal runaway.

2. The "blind spot" of traditional testing

The embarrassment of water testing: the housing needs to be dried after the immersion test, which may introduce moisture corrosion risks.

Limitations of pressure testing: only large leaks can be detected, and micro leaks of ≤10⁻⁶ mbar·l/s are helpless - this is equivalent to leaking a sesame-sized helium every year.

Industry truth: 90% of ceramic housing failure cases are due to "nano-level vulnerabilities" that traditional testing methods fail to detect.

2. Helium inspection technology: the scientific magic that makes the "invisible killer" nowhere to hide

Imagine: helium is like a group of well-trained "scouts", and the helium detector is their command center.

1. Ultra-sensitive "leak detection" principle

Molecular penetration: The diameter of helium molecules is only 0.26 nanometers, which can drill into the 0.1 micron defect of the ceramic shell.

Accurate tracking: The helium mass spectrometer is like a "gas radar", which can detect leak rates as low as 5×10⁻¹⁰ mbar·l/s (1000 times more sensitive than traditional methods).

Non-destructive testing: No need to contact liquid, avoid shell contamination, especially suitable for the cleanliness requirements of high-voltage DC relays.

Case report: After a supplier in Jakarta, Indonesia introduced an automatic helium detector, it successfully passed the German Rhine TÜV certification, won orders from European car companies, and increased its annual export volume by 200%.

3. Automatic helium inspection machine: "efficiency-enhancing and burden-reducing magic weapon" for Southeast Asian factories

For Southeast Asian manufacturers who are sensitive to labor costs, the value of this equipment is far more than "quality inspection" - it is also an invisible engine for profit growth.

1. Speed revolution: faster than cooking a bowl of Vietnamese rice noodles

Multiple vacuum boxes are used for parallel inspection, and the time for a single piece is ≤15 seconds. More than 2,000 pieces can be inspected in 8 hours.

The code scanning traceability system automatically associates production batches, and the source of quality problems is located in 30 seconds.

2. Helium circulation: saving real money

Helium prices fluctuate violently (the increase in 2024 is more than 30%), but through the 95% recovery rate design, a single device can save about 80,000 US dollars in helium costs per year - enough to add another production line!

3. Flexible intelligent manufacturing: one machine for multiple uses

The modular design is suitable for ceramic shells of different sizes, from high-voltage DC relays for new energy vehicles to charging pile seals, and can be quickly changed in 5 minutes.

Intelligent pressure regulation (0.1-1.0MPa) matches a variety of test scenarios.

Future vision: When helium inspection machine meets AIoT

Intelligent prediction: Through machine learning, analyze historical data and reduce the defect rate.

Cross-border collaboration: Real-time remote generation of optimization solutions based on inspection data.

In the trend of "high voltage" and "fast charging" in electric vehicles, every tiny crack in the ceramic housing may cause the company's hard-earned brand reputation to collapse. An automatic helium inspection machine is not only the "gatekeeper" of quality, but also the "golden key" of the relay product line.

All-solid-state battery cars: no mileage limit, a new driving force for future travel

All-solid-state battery cars use solid electrolytes to replace the liquid electrolytes in traditional lithium-ion batteries, and store and release electrical energy through the migration of lithium ions between the positive and negative electrodes. This new type of battery uses solid conductive materials, which fundamentally solves the safety hazards of liquid electrolytes.

Why is helium leak detection the "safety gatekeeper" of all-solid-state batteries?

Although all-solid-state batteries use solid electrolytes instead of flammable liquid materials, minor defects in the battery packaging process may still cause gas leakage or moisture intrusion, causing performance degradation or even safety hazards. Helium (He), as an inert gas, has extremely small molecules (only 0.26 nanometers in diameter) and can accurately detect micron-level leaks. It is the "gold standard" for detecting battery air tightness.

The automatic helium inspection machine for automotive parts developed by HCTE uses a high-precision helium mass spectrometer leak detector, which can complete the battery pack sealing test within 10 seconds with a sensitivity of up to 5×10⁻⁸ mbar·Ls. By simulating complex working conditions such as vibration and temperature changes during vehicle driving, the equipment ensures that each battery meets the IP67 protection standard before mass production, completely eliminating the risk of "a thousand-mile dam collapsed by an ant hole".

HCTE Helium Inspection Machine: The Key Driver of Mass Production of All-Solid-State Batteries

The commercialization of all-solid-state batteries faces two major bottlenecks: high interface impedance and high manufacturing costs. HCTE's automated helium inspection technology is breaking through from the following dimensions:

1. Cost reduction and efficiency improvement: Traditional helium inspection relies on manual operation, which is inefficient and has a high error rate. HCTE equipment supports fully automatic assembly line integration, with a 300% increase in inspection efficiency. A single device can inspect up to 500,000 sets of batteries per year, helping automakers to quickly achieve large-scale production.

2. Extend life: By accurately locating and repairing micro-leakage points, the battery cycle life is increased by more than 20%, directly reducing users' "battery anxiety".

3. Compatible with future technologies: Whether it is a sulfide electrolyte or an oxide system, the HCTE helium inspection machine can be adapted, providing "zero compromise" quality assurance for the development of next-generation solid-state batteries.

Data speaks: How does helium leak detection rewrite the rules of the game in the industry?

Safety improvement: The fire accident rate of battery packs equipped with HCTE helium detectors has decreased by 95%.

Endurance optimization: After the airtightness meets the standard, the battery energy loss is reduced by 8%, and the endurance mileage has steadily exceeded 800 kilometers.

Customer case: After a leading car company adopted HCTE equipment, the battery recall rate dropped by 92%, and the annual cost savings exceeded 200 million yuan.

The future has come: In 2030, how will all-solid-state batteries change your travel?

Industry forecasts show that all-solid-state batteries will occupy 30% of the new energy market in 2030, and helium leak detection technology will become the "invisible engine" of this process. As the world's leading leak detection solution provider, HCTE has reached strategic cooperation with various battery manufacturers. Its modern automatic helium detector has introduced blockchain traceability technology to "chain" the detection data of each battery and provide users with a lifetime warranty certificate.
