There might be a lot of molding companies available around your location but selecting the best plastic injection molding company is always a difficult task. Lets find the steps to be followed while choosing the company.
Plastic injection molding is a process of manufacturing thermoplastic and thermosetting plastics. Plastic injection molding constitutes different stages in which the material is first sent through a hot barrel and melted down for mixing and then it is sent into a mold to cool and solidify in to the shape of the mold. Evaluating a plastic molding company Considering the cost Learning the history Finding their capabilities and specialties Considering quality of the molder and delivery time Finding the quality of the products produced Considering the location of the supplier The first and foremost thing to know when evaluating a plastic molding company is finding what you need them to mold for you. You must prepare a completely defined 3d model of the plastic component along with specifying the draft angles, surface textures and maximum allowable flash. The next factor to realize when choosing an injection molding company is the cost. Buying the products in China or Korea would be much cheaper but the delay in getting the product would be more. You need to be wiser when choosing and you should also consider the restrictions on price based on the project your company is working on. The next important thing to consider is learning the history of the company and their potential. Try to find how long they have been on business and what industries do they work for? If you need to manufacture a product that requires tight tolerances, it would be better to choose a plastic molding company that deals with health or aeronautics industry than a company that molds toys. Once you have known the background, try to find their capabilities, specialties, the presses they use and how old they are? Also find if they would be able to handle the volume you require? Apart from considering the lower component cost, you should also consider the quality of the molder and the delivery time. Lower molding costs wouldn't be an overall savings for you always if there is a high delay in delivery and the product is of lower quality. Take some time to find the quality of the products produced by the company. Also check if they are a certified company and they do control charting? What would be their action plan if they find an useless product during audit? The final thing to consider is the location of the supplier and how will this impact on your working relationship? Choosing an injection molding company near your location would be much better than choosing a company overseas because you can just visit your supplier any time when issues arise instead of spending thousands of dollars per visit.
