Why Precision Dispensing Is Required
Manual dispensing relies on operator experience, resulting in unstable glue volume control. Issues such as glue accumulation, leakage and stringing frequently occur, making yield hard to guarantee.
Growing Encapsulation Demands for LED Lighting ModulesProcesses including LED encapsulation, module potting and lens bonding require precise glue application at multiple positions on LED modules. Encapsulation materials such as silicone and potting compound feature high viscosity. Manual dispensing struggles to control glue volume and position, which easily causes uneven potting or air bubbles. The 600×600mm working travel of SIE‑302 fits LED module dimensions. Multi‑head mode enables simultaneous dispensing on multiple modules to improve encapsulation efficiency. ±0.02mm accuracy ensures accurate potting position, compatible with LED encapsulation materials such as silicone, potting adhesive and speaker adhesive. | Sealing & Dispensing for Automotive Electronic ComponentsAutomotive electronic processes such as lamp sealing, ECU potting and sensor fixing impose strict requirements on dispensing consistency and sealing performance. Dozens of dispensing procedures are involved in one vehicle, and different adhesives (sealant, hot‑melt adhesive, structural adhesive) are applied for various components. Manual operation cannot guarantee consistent quality. SIE‑302 supports multi‑variety program storage for quick changeover by recalling corresponding programs. One machine handles dispensing for multiple automotive electronic parts. Multi‑head mode boosts mass‑production efficiency, and ±0.02mm accuracy ensures reliable sealing quality. | Coating for Housings & Wiring Harnesses in Home Appliance ManufacturingProcesses such as home‑appliance housing sealing, wiring harness fixing and shock‑absorbing coating require large‑area and multi‑point glue application. Materials including hot‑melt adhesive, foam adhesive and sealant need uniform coating on housing seams and wiring harness joints. The 600×600mm working travel of SIE‑302 covers dimensions of most home‑appliance products. Four‑axis linkage supports coating on curved and vertical surfaces, and multi‑head mode accelerates tact time for mass‑production home‑appliance lines. |
✨ Dilemmas of traditional dispensing: Manual dispensing has low efficiency, poor consistency and unstable yield. Semi‑automatic dispensers only perform planar dispensing and cannot handle 3D curved surfaces. Single‑head dispensers deliver limited efficiency and cannot satisfy mass‑production tact time. Conventional dispensers require complex programming with long changeover time, not suitable for multi‑variety production.
Why Choose SIE‑302
Solve Dispenser Selection Pain Points for Medium‑sized Products
Flexible & Efficient Single‑head / Multi‑head Dual ModesSupports both single‑head and multi‑head working modes for flexible adaptation to various production scenarios. Single‑head mode prioritizes accuracy for multi‑variant small‑batch production; multi‑head mode boosts productivity with simultaneous operation of multiple dispensing heads for low‑variant mass production. Use single‑head mode for program debugging in R&D phase and switch to multi‑head mode for mass production. One machine covers the whole process from development to mass production. Max load 20kg, compatible with medium‑sized products and fixtures. | Full‑coverage 600×600mm Working Travel600×600×100mm working travel fits medium‑sized products such as LED modules, automotive electronic components, home appliances and acoustic devices. Compact footprint for standard workshop deployment. Four‑axis linkage enables dispensing on 3D, inclined and curved surfaces, meeting diverse dispensing path requirements. | Program Storage for Fast Multi‑variant SwitchoverSupports on‑site programming via teach pendant and CAD / CORELDRAW programming on PC. Stored programs can be recalled directly without reprogramming for quick product changeover. Ideal for flexible multi‑variety production and reduces downtime for changeover. Timing‑belt plus guide‑rail transmission, moving speed 0.1‑500mm/s, balancing efficiency and stability. |
✨ If you require dispensing for medium‑sized products, multi‑head efficiency improvement or flexible multi‑variant production changeover, SIE‑302 is your ideal choice.
