Which factors will affect the maintenance for these injection molds?
Sep 8, 2014-China-It's important to remember that the total cost of an injection molding tool is more than the price stated on the quote. The full injection mold price includes two parts the initial cost, the price listed on the quote and the residual costs, expenses that start once a new mold is in production and occur over the life of a mold. Many variables will affect both of these costs and, ultimately, the final price. Now, the famous Injection mold company in china which website is www.plasticmouldmaking.com will introduce with people these factors.
The purchase price is influenced by the following factors:
Part size and part designation
Large parts require large molds, resulting in greater material cost.Intricate part designs require elaborate mold designs, which generally increase the tool cost. Simple part designs require less complexity in the mold design, lowering the cost of the tool.
If the plastic used is volatile or corrosive, requires high mold temperatures, or contains abrasive materials such as mineral, glass or carbon fiber, the cost of the tool might increase. These factors could also impact the maintenance cost of the mold (a residual cost).
Part tolerance strategy?
Parts with tight tolerances will require additional mold manufacturing steps, which increase both the manufacturing and tool maintenance costs (residual costs).
High-volume (think hours of production, not number of parts) projects need higher quality tools to provide reliable service, which increases the cost of the tool. A higher number of cavities are also associated with greater manufacturing costs.
In order to achieve fast machine cycles, a tool needs uniform cooling throughout the cavity impression (and from cavity to cavity in multi-cavity tools). This requires well-designed tooling and higher precision build, both of which increase the tool construction cost and potentially the maintenance cost.
Proper gate location is critical to part quality, but tools that do not have gates at the side of the part require construction techniques that increase tool cost. Additionally, the use of hot manifold systems significantly increases the tool price but frequently lowers the part price and/or tool complexity.
The mold functions like a heat exchanger, drawing heat from the molten plastic. Uniform cooling throughout the cavity impression will yield the highest quality part and the fastest cycle time. Different cooling strategies will impact the tooling manufacturing cost.
Design and Build
A well-designed mold has lower residual costs, is easier to set up and to start, has lower reject rates and a predictable and consistent cycle time, and will perform well beyond its required life expectancy. Your supplier will provide reliable quality, cost and delivery when using a properly designed, built and maintained mold. On the other hand, an unreliable tool impedes production and requires extra time and effort to repair.
Because residual costs occur over a period of time, they often remain hidden until later in the project lifecycle.?Any inefficiency in a mold such as defective parts, slowing cycle time, and tool wear can affect residual costs. The best way to reduce these costs is through good tool design and maintenance.?
