Rotational Molding

Additional savings come from lower economic run quantities and controlled material use meaning there is no wasted plastic- what goes into the mold comes out in your part. Plus, stronger plastic part can be made that replaces metal, wood, fiberglass and even other plastic pieces. In rotational moulding, polymer powder is slowly tumbled in a heated, enclosed mould. The powder melts, forming a coating over the internal surface of the mould. The mould is cooled, allowing the polymer coating to become solid. The mould is then opened, and an accurately shaped plastic part is extracted. rotomolding companies near me

As reliance on rotational molding expands rotomolded plastic components are adding customer value and earning their spot in a manufacturing process by replacing several parts with just one. By molding dissimilar pieces together and designing other features right into the mold, rotational molding adds flexibility and options for manufacturers that other plastic molding processes just can’t match.

Think of the broad impact of being able to do that: Fewer parts to stock, track and handle and easier assembly means reduced labor. Assembly labor is reduced when multiple parts are combined into just one. And in many cases assembly is eliminated altogether when the finished product is complete after molding. With no painting or finishing required, your part is ready to go out the door. Often vendors will drop ship your parts to your customer creating a virtual manufacturing center for your product. You never touch the part but earn your markup.

As the boundaries of what can be achieved with rotational molding keep getting pushed farther out, awareness of the savings that can be achieved making parts this way is growing. Companies of all sizes looking for lean manufacturing solutions in their own plants are giving it a second look. The payoff is more than just reduction in the cost to make the parts; companies are banking the savings from smoother processes and higher throughput.

Lean manufacturing and its emphasis on continuous process improvement has found its way into new solutions to old problems. Material handling adds no value to your product and becomes the obvious focus for cutting costs. Wasted labor steps bog down many manufacturing processes, especially in the food, meat and poultry and pharmaceutical processing industries. Work flows vary by company, work culture and how they evolved.

Few plants find off the shelf solutions that can maximize the improvement to be had in their manufacturing processes. For those willing to invest the time, they’ll discover they can have custom designed, plant specific products made that help them reclaim, labor, process time and space – with a substantially larger return on investment.

The better rotational molders take a consulting approach which leads to more exacting and cost saving solutions. Instead of peddling what they produce and trying to make it work, they seek out opportunities for process improvement for their customers. Using an alert eye for bottlenecks, they do value stream mapping of the customer’s operation from beginning to end. This can be a tedious process so you’ll want to work with a rotomolder with experience in lean manufacturing techniques.

This blended approach changes the whole dynamic of procurement. Instead of calling in a rotomolder to outsource parts, it now makes sense to invite them in to understand your operation and possibly uncover opportunities right under you nose.
