SHANGHAI FRANCOM ROTOMOLDING TECHNOLOGY CO.,LTD is set up in 2015. Our team and major engineers all have worked in rotational molding industry for more than 10 years, which makes FRANCOM a modern economic entity that concentrates on technological research, design development, manufacturing, trade and investment for rotational molds, rotomolding products.
Bearing mind that Innovation is the driving force of development. And technology is soul of Creation, workers in FRANCOM always stick to the path of technological creation in order to make sure that FRANCOM is the leading rotational molding manufacturer. In addition, Francom has introduced from home and abroad large-scale and high-end CNC machines, universal milling machines, digital controlled lathe, EDM machines, linear cutting machines, auto-shuttering machines and a dozen of big scale production equipment. By introducing those advanced manufacturing equipment. FRANCOM has become the leader of hardware. It has also joined in Rotomolding Professional Committee of China and Plastic Association of China in succession, which won the company a good social contact and public praise in rotational molding industry and further makes it a potential and qualified supplier. Engineers and workers here all elites who have years of experience in floor cleaning machines, outdoor and indoor playground equipment, kayaks and surf-boats, furniture, case and gardening planters.
As quality is the lifeblood of enterprise development, Francom always adheres to the concept of " No Quality, No Development" and determines to control quality at the source in order to build the idea of Total Quality Management (TQM). With rigorous management system , advanced production technique, and customer- focused service concept, FRANCOM has set up a strict quality standard so as to provide customers with constantly improved quality. FRANCOM has now won a good reputation in both domestic and foreign countries and the molds , products, rotomolding machine it produced have been exported to countries such as America, England.

1. Design & Engineering Services
Beginning a new project starts with a solid design concept. Our in-house Design & Engineering Department will help advise and manage your project all the way to a produced rototmolded part.
Whether your project is a rough idea or a 3D model, we believe in developing a partnership early on with the customer and strive to reduce lead times and so both parties benefit from rotational molding.
2. Rotational Molding Design Guides
· Minimum wall separation 5x wall thickness (a)
· Minimum wall separation 3x wall thickness (b)
· Uniform wall thickness ± 20% (c)
· ±10% is considered precise tolerance (c)
· Wall thickness .090" to 1.00" (c)
· Different wall thickness can be produced based on functional requirements
· Large flat areas need a crown or ribs (d)
· Corners need minimum radius of 3/16"(e)
· Structural strength
· Reinforcing ribs - average proportions
· Height 4x wall thickness (f)
· Width 5x wall thickness (g)
· Kiss-off ribbing (h)
· Part Finishing and Secondary Operations
Note: Design Guide information is based on Linear Low Density Polyethylene (LLDPE) other materials tolerance can vary.
3. Cast Tooling Pattern
When your design is finalized the pattern production begins. Most commonly patterns are CNC machined from the 3D model, but other options are available.
After the pattern is reviewed and signed-off on, the followers for determining the parting lines are constructed. Next, the pattern goes through the sand ramming process creating the cope and drag. Then our Tooling Department is ready to pour the tool.
4.Rotational Molding Plastic Parts
Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powder or liquid resin into a hollow mold and then rotating that tool bi-axially in an oven until the resin melts and coats the inside of the mold cavity. Next the tool is cooled and the part is removed from the mold.
