CHMING 1600W Hand Extrusion Welder Gun (110V)
The CHMING 1600W handheld extrusion welder is designed for welding HDPE, PP, PVDF, and related plastics. It features dual heating with a hot air system and an internal motor, capable of reaching 20-600℃ wind temperature and 200-380℃ extrusion temperature. With an extrusion rate of 2-2.5 kg/h and a welding rod diameter range of Φ3.0-4.0 mm, this unit supports welding narrow gaps and corners, making it suitable for plastic sheets, tanks, liners, and pipe work. Its light weight and stable performance are highlighted as advantages for field use or workshop projects.
CHMING 1600W Hand Extrusion Welder Gun (220V)
This variant mirrors the 110V model with 220V power, offering the same dual heating system and temperature range. It supports a 2-2.5 kg/h extrusion rate, 200-380℃ extrusion temperature, and Φ3.0-4.0 mm welding rods. The device is marketed for welding HDPE, PP, PVDF, and more, including applications in bitumen waterproofing, packaging materials, and pipe joining. The design emphasizes portability and efficient extrusion for tight spaces and complex welds.
CHMING 1600W Hand Extrusion Welder Gun (Black HDPE Rod)
This model is distinguished by an included 5 kg black HDPE electrode rod (4 mm diameter). It maintains the standard 1600W hot air and 800W motor setup, with a similar extrusion range and heating capabilities as other CHMING units. The availability of HDPE-specific welding rod makes it a convenient option for HDPE pipe work, tanks, and liners where HDPE welding is preferred for uniform material compatibility.
LESITE LST600A Handheld Plastic Welding Extruder
The LESITE LST600A integrates a 360° rotating welding head with real-time temperature display for the welding rod heater. It uses dual heating: a 1600W hot air blower for preheating parent material and an 800W internal heater for the welding rod. This design supports precise temperature control and versatile welding across HDPE, PP, PVDF, and LDPE, making it suitable for complex joints and varied material thickness.
LESITE LST600B Handheld Plastic Welding Extruder
The LESITE LST600B features independent control of extrusion and hot air heating, aiming to ensure consistent material melting and welding rod temperature. It includes motor starting protection to prevent cold-start damage and a microcomputer chip control for intuitive operation and strong protective features. This setup supports HDPE, PP, PVDF, and other plastics, with emphasis on safe operation and reliable welding results for pipes, sheets, and liners.
Buying Guide: Key Purchase Considerations
When selecting an HDPE pipe extrusion machine, consider these dimensions to match your needs:
- Voltage and power: Ensure compatibility with your electrical supply (110V vs 220V) and evaluate whether 1600W hot air plus 800W rod heating meets your work rate requirements.
- Temperature range: A wide extrusion temperature (roughly 200-380℃) enables melting different plastics and thick materials. Real-time monitoring helps prevent overheating and material degradation.
- Welding rod compatibility: Check rod diameter range (commonly 3.0-4.0 mm) and availability of HDPE-specific rods for consistent bonding.
- Heating system design: Dual heating (preheating material and rod) improves welding quality, especially on tight corners and narrow gaps.
- Head design and mobility: 360° rotating heads offer flexibility in awkward positions; lightweight builds reduce operator fatigue for extended sessions.
- Control features: Microcomputer control, temperature display, and protective measures (cold-start protection) help reduce operator error and equipment wear.
- Applications: Ensure the device supports HDPE, PP, PVDF, LDPE, and compatible materials; consider its suitability for tanks, liners, pipes, and bitumen applications.
- Maintenance and spare parts: Availability of replacement rods, heating elements, and customer support influence long-term costs and uptime.
Consider your workspace—whether a small shop or field site—along with your desired throughput. For critical HDPE piping projects, prioritize machines with precise temperature control, robust build quality, and reliable safety features. If you frequently work in tight quarters, a rotating head and light weight can significantly improve efficiency.
