1. Raw Material Specification
The dedicated raw material for solar water heater tail supports is PPE (Polyphenylene Ether) engineering plastic. Modified PPE materials are also commonly produced using modified formulations, making it a high-end special engineering plastic suitable for outdoor plumbing fittings. Only high-purity virgin PPE pellets are adopted as raw materials, free of recycled materials and impurity adulteration, delivering high material purity and outstanding stability.
PPE resin inherently features excellent rigidity, temperature resistance, weather resistance and insulating properties, alongside extremely low water absorption and superior dimensional stability. Tailored to the operating environment of solar water heaters — characterized by outdoor exposure to intense sunlight, wide temperature variations and high humidity — the raw material undergoes specialized modification and optimization to enhance resistance to aging, low-temperature embrittlement, ultraviolet radiation and water vapor corrosion. It perfectly fulfills the core functions of the tail support: load bearing, protection and fixation. Compared with ordinary ABS and PP plastics, it achieves drastically extended service life and greatly improved structural stability.
This product supports two types of raw materials for different specifications: PPE material exclusively for 47 mm vacuum tubes, and PPE material exclusively for 58 mm vacuum tubes. The fluidity and hardness of the raw materials are precisely adjusted according to tube diameters to guarantee consistent fitting performance and load-bearing capacity of finished products.
II. Core Performance Parameters of Raw Materials
This product adopts modified PPE material. Its core physical, mechanical and weather resistance performance parameters are listed below, complying with industry standards for outdoor solar accessories:
III. Product Manufacturing Process (Injection Molding Process)
This solar water heater tail support adopts high-precision injection molding machine one-step forming technology, with fully automated standardized production. The process is mature, featuring high finished product precision and low defect rate. The detailed production workflow is as follows:
Raw Material Pretreatment:Virgin PPE pellets are dried and dehumidified to thoroughly remove trace moisture inside the material. This prevents defects such as air bubbles, sink marks and cracking during injection molding, and ensures raw material purity and molding stability.
High-Temperature Melting & Plasticization:Dried PPE pellets are fed into precision injection molding machines. Segmented temperature-controlled heating enables uniform melting and plasticization of the material, ensuring consistent melt flowability suitable for forming intricate structures of both 47 mm and 58 mm tail supports.
High-Pressure Injection Molding:Custom dedicated molds (separate molds for 47 mm and 58 mm tube diameters) are used. Molten PPE is injected into mold cavities at high pressure and high speed to precisely fill all structures including clamping openings, supporting bases and fixing holes, guaranteeing complete product contours and standardized dimensions.
Constant-Temperature Cooling & Setting:Constant-temperature mold cooling and slow setting effectively reduce internal stress within products to prevent subsequent deformation and warpage, ensuring flatness and structural strength of the tail supports.
Ejection & Part Removal:Trimming and polishing are performed on finished product edges and clamping openings to remove tiny burrs. The clamping openings stay smooth so that the outer surface of vacuum tubes will not be scratched during installation.
Quality Inspection, Sorting & Packaging:Each unit is inspected for dimensional accuracy, hardness, clamping fitting performance and appearance integrity. Products are sorted and packaged by 47 mm and 58 mm specifications before warehousing.
Overall Process Advantages:One-piece forming leaves no assembly gaps. Products feature strong structural integrity, stable load-bearing capacity and high fracture resistance. Consistent dimensions in mass production deliver excellent interchangeability, compatible with supporting installation of various solar water heaters.
IV. Product Application Scenarios
This 47/58 mm PPE tail support for solar water heaters is a core matching component for solar vacuum collector tubes with great versatility. Its main application scenarios are listed below:
Household Wall-mounted / Rooftop Solar Water Heaters
Suitable for integrated solar water heaters installed on rooftops and balconies of rural self-built houses and urban residences. It matches vacuum collector tubes of 47 mm small diameter and 58 mm standard diameter respectively. It provides end support, fixation and buffering, preventing direct friction and collision between vacuum tubes and metal brackets so as to avoid tube breakage and water leakage.
Commercial Centralized Solar Hot Water Systems
Applicable to large centralized solar hot water projects for hotels, factories, schools, homestays, apartments and other premises. It serves as end fixing support for large arrays of vacuum collector tubes. With outstanding weather resistance, it adapts to long-term open-air outdoor working conditions and reduces project maintenance costs.
