Making cheap but quality plastic molds – why not?

One factor that customers are often interested in is how much it costs to make a plastic mold. On this issue, we would like to advise customers on the factors that determine the price of a plastic injection product.

• Accuracy: this is probably the most important factor that causes the price of making molds to increase. A plastic product with a size that requires an accuracy of 0.01mm – 0.1mm will cost much more than a product that requires an accuracy of 1mm or more. It can be understood as follows; “a product that requires precision requires more precise mold components. A mold component that requires precision requires a higher precision machine. The more precise the machine, the higher the purchase price of the machine… all of these factors push up the mold price”.
• Product shape: The simpler the product, the easier it is to make and achieve the purpose of use. On the contrary, products with complex shapes such as undercuts, threaded products, products that require slides, products that require high gloss… the mold structure will be complicated, taking a lot of time to design the mold, process the mold, and test many times. This process requires a considerable amount of cost.
• Product volume: The larger the product, the larger the mold. The cost of the mold will increase as the material used to make the mold increases.

The above are the two main factors that determine the cost of the mold. However, if you make a mold with us, customers can rest assured that they will not have to spend a large amount of money to make the mold.

• If the shape of the product is too complicated, it is necessary to improve the product to simplify the product but still ensure the features and technical requirements of the product.
• The volume of the product not only affects the cost of the mold but also affects the cost of the product. Many customers request to make products with too thick walls but it is not necessary. Thick mold walls are not necessarily good, uneven wall thickness will cause difficulties in the injection molding process such as deformation, dents, shrinkage … so the mold maker needs to calculate the product wall reasonably, make it as thin as possible to ensure the best product price for customers and at the same time reduce the mold cost.

In addition, there are a number of other factors such as the number of cores in a mold, 2-plate mold or core exchange mold, mold material … When receiving a customer’s request, it is necessary to research with the customer to reduce the cost to the lowest for the customer.
