Plastic Products and Mold Design

There are many factors to consider in mold making. To list some:

• Budget;
• Product material;
• Mold material;
• Wall thickness;
• Draft angle;

Take into consideration that a thin product (less than 0,4mm) require a higher clamping force to keep the mold closed without any damage to the product final aspect (burrs, sink marks, etc).

how to decide wall thickness of product?

The product designer must always have the budget in mind when designing a new product. Thicker walls means more plastic per piece, increasing the production cost. On the other hand, thin products usually are a pain to reach efficient production cycles, but can save a lot of money on plastic material. So, the first step is to talk with the customer and understand what he really expects with the new product.

There are lots of other variables on this matter. I hope our friends here can help with their considerations

merhabalar ben makina ressamlıgı ögrencisiyim ve plastik parçalarını tasarlıyorum ama kalıplayamıyorum kalıbını çıkaramıyorum bana yardımcı olurmusunuz? Erkek dişi oluşturamıyorum bazı plastik nesneleri numuneleri erkek dişi yapabiliyorum ama bazıları olmuyor yani ögrenmem lazım

Product thickness in plastic technical term is to consider the most effective cooling rate of plastic without giving the unwanted impact to its structure and appearance. With the right cooling channel design, in average you can go up to 3 to 4 mm thickness. But we also have to consider sustainability issue, therefore it will be good if we design as thin as possible to achieve the lightest product weight. To create the "user experience" feeling of product thickness you can build like a double wall product.

there is the ratio between flow vs plastic thickness, commonly called as F/t ratio and the general value is 220 it means that you can design a 220 mm plastic flow length with 1 mm thickness. But if you want to go thinner then you have to consider material viscosity and processing technique.
