Evaluating the Turnaround Times of Reaction Injection Molding (RIM)

Reaction Injection Molding (RIM) can produce a positive result and quick turnaround. Because RIM technology is widely known to produce one of the most powerful, resilient and affordable products on the market, people think that it is a slow process and might not yield a positive result. For a dependable reaction injection molding manufacturer, it should take at most one month to produce the finished product. If a consumer re-orders a particular product, there is a high chance that the items would be delivered at a faster pace. The RIM process will produce an efficient end-result and it will only take minutes for each item to get through the machine, yet it must be done with a high precision of set-up and finishing producing an excellent finished item.

RIM Production Process

For reaction injection molding processing to occur, it involves the thorough combination and fusion of two reactive liquid components, a polyol, and an isocyanate to produce a reaction in a closed pressure mold. The resulting product of the two components gives rise to polyurethane and depending on the level of pressure inside the frame, can result in either a lighter or denser substance. No matter the kind of texture or feel, it will have some features like thick, strong skin with a low bulk of cellular core, with great impact resistance and UV and the capability to resist chemical.

Complex parts can be incorporated with different features like thin and thick walls with a varying degree of durometer ratings (hardness). Also, the specs help determine the level of rebound, tear strength or low compression set features. With a new invention of a product, a reaction injection molding manufacturer may be able to invent a model for product advancement and testing, and this added feature may take additional time.

Often, an item being manufactured will have the incorporation of aluminum or glass form structures, bushings or steel, and a combination of metallic materials or a single piece. The added features will enhance the functionality of the material, so it must be molded to specific instructions. Consider the factors highlighted above and make your final decision.
