About us

our story

Trident Plastics is the largest custom moulder in SA offering a full suite of services from concept development, product design, prototyping, mould making and product manufacture to a diverse range of clients.

Plastic products have been made at the St Clair plant since the mid-1970s, but the formation of Trident Plastics in 1995 has allowed our services to expand from Toolmaker to Manufacturer and co-locate all services to the one site.

We configure our services to meet our customer’s specific requirements. Trident Plastics can offer exceptional flexibility in the products we can design and manufacture including value-added services such as non-plastic component pre-assembly.

Major clients include Climate Air Conditioning, HSV and Tier 1 supplier to GMH.
