The development of a coffee machine panel requires comprehensive consideration of functional requirements, material technology, interaction design, and production feasibility. The following analysis is presented from four dimensions: design process, key technologies, material selection, and process implementation.

1、 Demand Analysis
Function Definition: Identify core functions (such as temperature control, adjustment of grinding fineness, pre-infusion time, pressure display, etc.) and extended features (like network control, voice interaction, self-cleaning reminders).
User Portrait: Optimized design for home use (priority given to ease of operation) or commercial use (priority given to durability, multi-user mode) scenarios.
Competitive Analysis: Referencing mainstream models in the market (such as the touchscreen + physical button combination of Franke A300 and the rotary valve design of ZK-1858), distill differentiated selling points.
2、 Structural Design
Parting surface design: If the in-mold coating process is adopted (such as PC film covering the plastic surface), it is necessary to set up a positioning structure on the parting surface to ensure precise adhesion of the film.
Ejection Mechanism: For complex snap-fit features (such as inclined push rods and slider structures), it is necessary to design stepped sliding grooves or integrated sliders to prevent damage to the plastic parts.
Gating System: Depending on the plastic part structure, choose between a bull nose gate or a drop gate, and balance the flow channel design to minimize weld lines.
3、Interaction Design
Interface Layout: Place high-frequency operations (such as start/stop, mode switching) at the center of the panel, and low-frequency operations (such as parameter settings) at the edges.
Feedback Mechanism: Confirm operations through LED indicators, buzzers, or haptic feedback (such as vibrations) to enhance the user experience.
Accessible Design: Provides voice prompts or large font display for visually impaired users, in compliance with WCAG standards.

1、Temperature Control
PID Algorithm: Real-time monitoring of water temperature through NTC temperature sensor, combined with PID algorithm to control the error within ±1℃, ensuring extraction stability.
Heating System: Utilizes an instant water heater or Thermocoil heating tube to reduce preheating time
2、pressure monitoring
Pressure Sensor: Integrated 0-15 bar pressure sensor, real-time display of extraction pressure (optimal pressure for espresso machines is 9-10 bar).
Safety Valve: Set up a device for overpressure protection to prevent damage to equipment or potential safety hazards caused by excessive pressure.
3、network connectivity
Communication Module: Integrated Wi-Fi/Bluetooth module, supports remote control via mobile app (e.g. adjusting grind size, scheduling brew time).
4、Cloud platform: Firmware upgrades via OTA to fix vulnerabilities or add new features (such as custom drink recipes).
1、Case Material
High-end models: made with titanium alloy or carbon fiber reinforced plastic (CFRP), balancing lightweight and high strength (such as a 30% weight reduction in certain commercial models).
Mid-range models: choose anodized aluminum alloy or ceramic coating to enhance texture and wear resistance .
Economy Model: Utilizes recycled plastics or bamboo fiber composites to reduce costs and align with environmental trends.
2、Panel Material
Touch Screen: Made of tempered glass or acrylic, with AG etching (anti-glare) or AR coating (antireflection) on the surface to enhance display clarity.
Physical buttons: Choose from silicone or PC+ABS alloy, with a button lifespan of over 100,000 presses (for certain models, the feedback force of the buttons can be adjusted).
Decorative elements: Achieve a metallic texture (such as gun gray, rose gold) through PVD vacuum coating, or engrave the brand logo with laser to enhance recognition.
1、Injection Molding Process
In-Mold Lamination: A PC film is pre-positioned on the cavity surface, and through high-pressure injection molding, the plastic part and the film are formed as one piece, reducing the subsequent lamination process.
Micro Arc Oxidation: Micro arc oxidation treatment is applied to aluminum alloy panels, forming a dense oxide film (with a hardness of 1000-3000 HV) and enhancing wear resistance.
2、Surface treatment
Spraying Process: Using water-based coatings to replace solvent-based coatings, reducing VOC emissions.
Laser Engraving Process: By laser engraving parameters to identify or decorative patterns, permanent markings are achieved (such as certain models engraved with brand stories).
3、Assembly process
Modular Design: Integrating panels, control boards, sensors, etc. into independent modules simplifies the assembly process (e.g., reducing assembly time by 40% for certain models).
Automated Testing: Using a CCD visual inspection system to check the sensitivity of panel buttons, display dead pixels, etc., improving the yield rate.
