Pet Bottle Preform Mold Regular Maintenance Importance
Posted by preform nicole on October 12th, 2018
Regular maintenance is often a top priority in our minds for our biggest investments, whether in our personal or professional life. Think about your car, your house, maybe some of your appliances - we want to make sure that we stay ahead and catch any major problems before any problems arise, so we carry out regular maintenance and "checks" to make sure everything is ok. Running.

Therefore, the maintenance of Pet Bottle Preform molds should be a major problem that makes sense. These molds typically cost tens of thousands or hundreds of thousands of dollars—usually more expensive than your car and may even be more expensive than your home. Why not take regular maintenance to protect and maximize your investment?
The maintenance of the injection molding machine is equally important in this process – although not overlooked – in part. We will study why the maintenance of injection molds and the machines they pass through are important to you, your bottom line and the quality of your parts.
What kind of problems will occur with injection molds?
Injection molds are subject to large stresses during the forming process. Depending on the design of the mold, temperature fluctuations, mold opening and closing, ram action and other movements can cause the mold to wear naturally. A good injection mold will be designed to handle this wear, but due to these large amounts of stress and the myriad of arrangements in which they can interact, unpredictable conditions will still occur.
For example, temperature fluctuations can cause internal and external stresses on the mold. In particular, if the design of the mold does not allow for more uniform cooling, the mold will expand and contract with heating and cooling, and will weaken due to stress, and may even break.
The "moving parts" of the mold are susceptible to friction, "rough" contact points and mechanical failure. For example, a mold that cannot be opened and closed smoothly may be affected by impact stress because the two halves will meet. After a certain number of molding cycles, the ejector pin may not work properly. In addition, the friction of the moving parts, in addition to generating additional heat, may eventually wear at critical parts of the mold, creating unexpected cavity shapes or damaged contact points.
In addition to the inherent aspects of the mold itself, there are maintenance issues associated with the material being injected into the mold. As the mold completes more and more cycles, a small amount of material residue will begin to collect in the mold cavity. Over time, these deposits accumulate and affect the internal shape of the cavity, affecting the shape of the final part. Deposits in the mold runner or cavity also affect the cycle time and, if left unchecked, may even begin to prevent the substrate from reaching the area of the mold.
If the mold is used with different materials, these deposits may also produce unexpected interactions depending on the chemical composition of these materials. This in turn affects the structural integrity of the finished product and poses a risk to the products used in food or medical applications.
