The rotational molding process is a high-temperature, low-pressure plastic-forming process that uses heat and biaxial rotation (i.e., rotation on two axes) to produce hollow, one-piece parts. […]
Rock and roll machineThis is a specialized single arm machine. It rotates or rolls the mold 360 degrees in one direction and at the same time tips and rocks the mold 45 degrees above or below horizontal in the other direction. […]
Molds (or tooling) are either fabricated from welded sheet steel or cast. The fabrication method is often driven by part size and complexity; most intricate parts are likely made out of cast tooling. […]
In 1855 R. Peters of Britain documented the first use of biaxial rotation and heat. This rotational molding process was used to create metal artillery shells and other hollow vessels. The main purpose of using rotational molding was to create consistency in wall thickness and density. In 1905 in the United States F.A. Voelke used [...]
Rotational molding, also known as rotomolding, is a molding process for creating many kinds of mostly hollow items, typically of plastic. […]
Recently, several ERP software vendors have made a major effort to address the challenges of engineer-to-order companies like moldmakers. […]
If the IT or production manager is trying to implement a system that the CEO/CFO or other department heads do not agree with, then there is little or no hope of getting others on board, or indeed getting budget allocated to acquire a suitable system. […]
MRP or manufacturing resource planning takes ownership of the data from the quotation stage, through the sale, the raising of the works order, through all stages of production including the warehouse (goods in/out) and subcontracting, through to shipping and invoicing. By holding a single source of data all departments should have visibility of relevant information. [...]
As a business grows, fragmented processes often develop with it. For example, those involved in production/manufacturing planning may use an Excel spreadsheet to track orders through the various stages of manufacture, but this will not talk to sales, warehouse or shipping—each of which may have their own system. Companies have even been known to plan [...]
Calculating the level of business opportunity involved with transfers depends highly on efficiency and due diligence of the process. […]
