Changzhou Xionghua Tongtai Automation Equipment Co., Ltd.

Changzhou Xionghua Tongtai Automation Equipment Co., Ltd. is based in China and currently lists five distinct products in its catalogue. The product lineup consists of four variants of programmable timer relays - standard relay, 8/i and 8/o models, an 8‑output relay model XHST‑30, and an 8/16‑output relay - as well as a hot‑runner mold temperature controller used in plastic processing. All relay items fall under the electric relay category, while the temperature controller belongs to the plastic processing machinery segment. The catalogue does not provide HS codes, but the items correspond to typical HS headings for electronic control devices and molding equipment. The company is classified as an imported supplier with a harbor trust tier.

The supplier’s catalogue features programmable timer relays with configurable on/off intervals and multiple output channels, plus a hot‑runner mold temperature controller for maintaining melt temperature during injection molding. In the relay market, common specifications include input voltage ranges of 110‑240 V AC, timing ranges from 0.1 s to 99 h, load current ratings up to 10 A, and contact materials such as silver‑cadmium oxide. IEC 61810 and IEC 60730 define performance and safety criteria that buyers typically compare against. For hot‑runner temperature controllers, industry standards often specify temperature ranges of 0 °C to 300 °C, PID control loops, and display resolutions of 0.1 °C. Buyers also look for compliance with CE, UL, and ISO 9001 certifications, which are widely accepted for both electrical control devices and plastic processing machinery.
