1. Engineered for Efficiency: The Box Feed Advantage

The "B" in OptiFlex 2-B signifies the Box Feed system. Unlike traditional hopper-fed units, this model is designed to draw powder directly from the original manufacturer’s cardboard container. This is not just a convenience; it is a strategic advantage for modern coating shops that prioritize lean manufacturing.

• Elimination of Powder Waste: The unit features an inclined vibrating base that ensures the powder flows toward the suction tube, emptying the box completely and reducing material overhead.
• Rapid Color Shifts: For businesses handling small batches of various colors, the OptiFlex 2-B allows for a complete color change in under 3 minutes. Simply swap the box and use the PowerClean™ function.

2. Advanced Technology: PCC and High-Voltage Precision

What makes a Gema gun superior to generic alternatives? It lies in the precision of the electrical charge and the fluidization of the powder particles. The OptiFlex 2-B integrates two critical technologies that define industrial performance:

Precise Charge Control (PCC)

When coating complex shapes or re-coating parts, back-ionization often causes "orange peel" textures or poor adhesion. The PCC mode allows operators to adjust the current below 10 microamperes (µA) with extreme accuracy. This ensures that even metallic powders or thick coatings are applied smoothly without sparks or surface defects, providing a premium aesthetic finish.

100 kV High-Voltage Cascade

The gun features an integrated 100 kV cascade that maximizes the First Pass Transfer Efficiency (FPTE). By ensuring more powder adheres to the workpiece on the first spray, you significantly reduce the amount of "overspray" that goes into the recovery system, directly cutting your material costs and increasing throughput.

4. Maintenance Guide for Long-Term Reliability

To maintain the high performance of your OptiFlex 2-B, Bangle Machinery recommends a proactive maintenance schedule to prevent downtime:

"Regular inspection of wear parts like the injector sleeve and spray nozzles can prevent 90% of coating quality issues in manual lines."

1. Shift Change Cleaning: Use the PowerClean™ function to flush the gun and hose. This prevents powder accumulation and impact fusion within the gun body.
2. Weekly Wear Check: Inspect the powder injector (venturi) and replace the insert sleeve if it shows signs of wear. A worn sleeve will cause "pulsing" or inconsistent powder flow.
3. Environmental Grounding: Check the ground connection of the unit and the workpiece hooks. Proper grounding is the most critical factor for both safety and high-quality coating.

5. Frequently Asked Questions (FAQ)

Q: Can the OptiFlex 2-B handle metallic or textured powders?

A: Absolutely. By utilizing the PCC mode and the appropriate nozzle selection, the OptiFlex 2-B provides excellent charging control for metallic flakes, preventing uneven distribution and sparking.

Q: How does the Box Feed compare to Hopper Feed?

A: Box Feed is superior for those who change colors frequently. Hopper feed is better suited for continuous production of a single color where the powder needs to be fluidized in bulk.

16 types of "Cream wind" integrated wall panel background wall, such a beautiful design!

 Romantic and comfortable, never out of style.

As a new collocation style that has captured countless young people, cream style, with its light

and gentle texture like cream, creates more light sweetness and space charm for home design.

The Cream style series launched by Merrypoint 2022 provides infinite inspiration for the realization

of personalized background wall customization.

Occasionally, the texture characteristics close to the log will be used to introduce it into the interior,

so that people can enjoy the beautiful solitude of peace and quiet, and enjoy the ideal life at leisure.

The light warm tone is refreshing, bringing healing and relaxation.

The complex design and layout techniques are abandoned, and the visual effects are displayed in

a simple state,showing the natural connection and transition between regions.

Happiness is often hidden in the details of life.

When the gentle and moving cream wind flows in every corner of the space, what unfolds is no

longer just the complicated self, but the real inner and deep exploration of meaning.

I love cream because I love the healing atmosphere it creates. Simple and gentle, enough to calm

the external noise

invasion, subtraction for life.

Heat Pump Thermostat

 Over the past decade, the European market for heat pumps has been growing at a steady pace, with an annual growth rate of 10% from 2011 to 2020, resulting in the expected installation of 1 million heat pumps per year in in the year of 2021, indicating a market growth of 39% from 20201. In the next decade, by 2030, we do not only see a growth, but an actual acceleration of the yearly installation of heat pumps that will go up to 4 million, representing an annual growth rate of 20%. In other words, 1 out of 3 heating systems installed is going to be a heat pump, from 1 out of 10 in 2020. Although this shows a steep growth versus past years, we consider this as a minimum to move to a decarbonised residential heating market in Europe.

The key driver for growth has undoubtedly been the introduction of strengthened legislation governing new builds in many European countries, ranging from general regulations in France such as RT2012, which sets the new minimum standard of thermal insulation of dwellings, to a ban on combustion boilers in the Netherlands.

 

Alongside this, E-Top has been working on replacement heat pump thermostat solution. We have released wired digital heat pump thermostat, wireless heat pump thermostat, smart wifi zigbee heat pump thermostat. All are heating and cooling programmable thermostat suitable for heating in winter and cooling in summer. We also provide ODM services. Any inquiry, welcomed to contact us from info@etopcontrols.com

Battery Fast Charging Performance Test | Battery Charging Test

 The purpose of the battery charging performance test is to check the charging ability of the lithium-ion battery in different states. Battery charging performance test includes battery slow charging performance test and battery fast charging performance test.

Among them, battery fast charging refers to the mode of charging at a higher current rate. Fast charging is usually the act of charging at high current rates in a low SOC state of the battery system.

Battery fast charging performance tests were conducted at designed current rates in low, normal and high temperature environments. The specific test procedure is as follows.

1) Discharge the battery to the specified discharge cut-off conditions in a specific discharge procedure at ambient temperature.

2) The battery is left to stand at the target temperature.

3) At the target temperature, charge the battery with the set charging method until the charging cut-off condition, and record the charging capacity, charging energy and charging time. In addition, the internal temperature difference of the battery system at the end of charging needs to be recorded.

4) Put the battery in a normal temperature environment until the temperature is balanced.

5) Discharge the battery to the specified discharge cut-off conditions in a specific discharge procedure at ambient temperature, and record the discharging capacity and discharging energy.

Record the test results in Table 1-1.

Table 1-1 Record Sheet of Battery Fast Charging Performance Test

NO.	Condition	Charging time	Charging capacity	Charging energy	Temperature difference	discharging capacity	Discharging energy
1	Low temperature
2	Normal temperature
3	High temperature
Kindly reminder: Temperature chamber and battery test equipment are necessary equipment for battery charging performance test.
