BMC Ladder Insulator Mould Successfully Developed by Taizhou Huangyan Tianqin Mould & Plastic

Taizhou Huangyan Tianqin Mould & Plastic, a professional manufacturer specializing in BMC composite moulds, has completed the development of a new 1+1 cavities mould for red ladder-type BMC busbar insulators.

This ladder insulator is widely used as busbar support in low-voltage switchgear and power distribution cabinets. Made from BMC (Bulk Molding Compound), the red insulator features excellent flame retardancy, high mechanical strength and stable insulation performance. Its special ladder/trapezoidal structure ensures reliable fixing of copper busbars under continuous operating voltage.

The newly built mould adopts a 1+1 cavity design, which balances production efficiency and product quality. It is manufactured for hot compression molding of BMC material, with precise cavity machining to guarantee consistent product dimensions and smooth surface. The mould structure is optimized for easy demoulding and long service life, reducing customer’s maintenance cost during mass production.

Tianqin Mould has rich experience in designing and manufacturing BMC thermoset moulds for electrical insulation components, including insulators, junction boxes and power accessories. The company can customize moulds according to customers’ drawings or samples, providing one-stop solutions from mould design, machining, trial molding to sample delivery.

With strict quality control and CE-compliant product support, Tianqin serves global clients in power transmission and distribution industry. The successful trial of this ladder insulator mould further expands its product portfolio of BMC electrical moulds, helping overseas buyers obtain stable and cost-effective composite insulator moulds and finished BMC insulators.
