CASE STUDY: Feasible Plastics
Tooling for Large Injection Moulded Bolt and Nut for Floating Solar Assembly
2024/25
Feasible Plastics Pty Ltd is a dynamic South African SME established in November 2020 through the strategic merger of BDM Plastics and RM Plastics. Based in Rosslyn, Pretoria, the company was founded by five directors: Bushy Mahadulula, Martin Thobejane, Rachel Rallele, David Bolayi, and Silas Rallele, with a shared vision to innovate within the plastic injection moulding sector.
Since inception, Feasible Plastics has evolved from a small component manufacturer into a competitive supplier for high-demand sectors such as automotive, aerospace, medical devices, home appliances, and packaging. The company continues to build on its foundation of technical excellence and industry responsiveness.
Offering end-to-end injection moulding services, including custom mould design, tooling, and finishing, Feasible Plastics is distinguished by its quality output and ability to manage complex projects. Its portfolio includes millions of precision components delivered to major clients, supported by a skilled team and advanced manufacturing equipment. The Small Enterprise Development Agency SEDA has played a vital role in the company’s growth, providing marketing, technical support, and branding assistance that enabled facility upgrades and increased production capacity. With plans underway for ISO 9001:2015 certification and premises expansion, Feasible Plastics is positioning itself as a scalable, trusted supplier within both domestic and regional markets.
The project supported by the AISI sought to secure the necessary tooling and qualify the manufacturing process for producing injection moulded bolts and nuts specifically for the floating PV systems market. Unlike current imports, the locally produced components will be designed to meet specific structural requirements not yet addressed by existing products. This targeted innovation not only offers a cost-effective, locally manufactured solution but also enhances supply chain resilience and reduces dependency on imported components.
The broader goal of the project is to establish a sustainable production line for large injection moulded bolt and nut components, primarily intended for assembly in floating solar panel systems, but with wider applications in other sectors. The commissioning of production tooling will allow for the manufacturing of test pieces and eventual market rollout. With an existing client base and export facilitation underway, Feasible Plastics is well-positioned to expand its footprint in the renewable energy sector, supporting local industrial development and contributing to South Africa’s green economy goals.
“The support received from the CSIR, the Aerospace Industry Support Initiative (AISI), and the Department of Trade, Industry and Competition (the dtic) has been instrumental in helping us meet one of our biggest challenges, developing custom moulds to meet specific client requirements. This assistance enabled us to design and produce a mould tailored to a key client’s needs, giving us a competitive edge, driving business growth, and creating new job opportunities. Access to similar funding in the future would further strengthen our ability to innovate, differentiate ourselves from competitors, and unlock new market opportunities,” says David Bolayi of Feasible Plastics.
