Involved in the design and development of a fluid reservoir, windshield washer reservoir, radiator surge tank, or coolant surge tank? Regency has your needs covered.

Regency Plastics has the engineering expertise to help your company develop or refine your blow molded fluid reservoir design in order to optimize part performance while driving cost out of your product.

We offer In-house Tooling services which eliminate non value-added time and cost associated with engineering changes.

Blow Molded Windshield Washer Reservoirs

By partnering with Regency Plastics, a major Tier 1 automotive company saved approximately $76,000 on tooling costs. This was achieved by optimizing part design of the windshield washer reservoirs. Further savings were achieved as Regency worked in coordination with sister company Thumb Plastics (Injection Molding) to supply the reservoir cap.

By utilizing In-house Tooling capabilities and partnering with Thumb Plastics (Injection Molding and Insert Molding), Regency was able to not only decrease overall cost of the windshield washer reservoirs, but also shorten time to market. Our customers tell us that in most cases, our lead times are 2 to 4 weeks shorter than our competitors.

We also specialize in Insert Blow Molding which allows us to integrate molded ports, clips, and brackets into your fluid reservoir assembly during the molding step of the manufacturing process. This eliminates the need for secondary assembly processes such as welding.
