In the case of everyday products, products that don’t need a precise injection process (such as utensils), the moulds are simple; plastics used in the engineering fields, on the other hand, such as those used in vehicles, for example, or for electronic products, telephones, mobile phones, among others, moulding must be more precise, the moulds are more complex, which means that the tooling is more exacting. This is where Rectimold comes in.
The mould is projected based on the plastic object to be produced, i.e., the end product. A draughtsperson creates a 2D and 3D design of the plastic item and then we use specific software to simulate the mould-making process and ensure that the mould is performing correctly, minimising any possible mistakes during production.
Moulds are generally made of steel – and these are the only type of moulds produced by Rectimold. The moulds consist of two parts: the stationary part (the Cavity) and the moving part (the Core). The injection system – which injects the plastic into the cavities – is located in the stationary part.
The mould can be projected to include one, two, or even more than 94 cavities. In other words, it can produce one, two, or over 94 plastic parts per cycle. The number of cavities depends mostly on the number of plastic items that the end client wants made per day.
The manufacturing process begins with the draughtsperson who, based on the size of the object produced, establishes the size of the mould and how it will operate. This phase involves several people, including the client, the mould maker, and even the suppliers of all the different materials needed to make the said mould.
Once a detailed Plan of all the stages has been set out, the mould is then manufactured. The steel goes through the Machining process, which can include different processes Itself, including conventional Milling, high-speed Milling or CNC, Erosion (wire erosion and electro-erosion penetration), and Rectification.
All parts produced are measured (they go through Dimensional Control) to ensure that all parameters are met. Once this process is over, the different parts of the mould are assembled and any necessary corrections and adjustments are made. The mould then goes through injection testing to validate the final product – the plastic part.
The mould-making sector is in great demand, and that means that top quality technology and expert workers are needed to guarantee that each client’s specific requirements are met. Rectimold is proud to have achieved and perfected each of these elements, and is proud of the experience gained since it first began operating over 30 years ago.
