Why choose us?

Diverse Tower and Internals Supply

We provide a wide range of towers and internals in materials like special alloys, ceramics, graphite, plastic, and stainless steel. Liquid distributors (orifice, trough, ladder, spray nozzle types) and gas distributor spargers are designed for uniform distribution, considering scaling/foaming factors. Packing supports, bed limiters, and mist eliminators (mesh/chevron types) are offered to enhance purity and prevent equipment damage.

Comprehensive Chemical Technology Support

With an expert team, we offer full-cycle technical support and consulting for R&D, production, process optimization, supply chain management, and environmental compliance. Services include process optimization to boost efficiency, sustainability solutions for regulatory compliance, safety risk management, IP protection strategies, and supply chain integration to reduce costs.

High-Quality Industrial Equipment Provision

Specializing in chemical industry equipment, we offer top-grade materials resistant to corrosive/abrasive chemicals (solvents, acids, oils, etc.). Product lines include diverse pumps (barrel, pneumatic diaphragm, centrifugal) and customized skid-mounted systems for single-point connection. All equipment meets API standards, with pumps complying with ANSI for guaranteed reliability.

Although injection moulding equipment is not a core product, the company provides technical support for process optimization and material selection in injection moulding applications. This involves polymer characterization (melt flow index, shrinkage rate) to ensure compatibility with moulding parameters (injection pressure 80–150 MPa, melt temperature 180–300°C). For complex components, the company offers mould flow simulation services (using Autodesk Moldflow) to predict weld lines, air traps, and shrinkage defects, enabling design adjustments to enhance part quality. Material recommendations are tailored to application needs, such as glass fibre-reinforced PA6 for automotive under-the-hood components (heat resistance >150°C) or flame-retardant PC/ABS blends for electronic enclosures (UL94 V-0 rating). Contact our application engineers for customized solutions, including troubleshooting moulding issues (short shots, burring) and optimizing cycle times (with 10–20% reduction).
