What determines the price of plastic?
- Crude oil price fluctuations
- Price difference by type
- Price difference by manufacturing method
- Consider material selection based on manufacturing costs
Parts that are mass-produced are generally produced using “machines”. Insert nuts are also produced by machines, excluding special ones, but each machine produced has different characteristics. Therefore, I will explain the characteristics of the machine that produces insert nuts.
Crude oil price fluctuations
The raw material for plastic is “oil”.
In other words, if the price of crude oil rises, the cost of manufacturing plastics will increase, and the selling price will also rise.
In addition, since the rise in crude oil prices will lead to an increase in transportation costs, the rise in crude oil prices, not limited to plastics, will lead to logistics costs for various products and associated price increases.
Price difference by type
There are many types of plastics.
And the price of plastic varies by type, but there is a correlation with "heat-resistant temperature".
Basically, plastics with excellent heat resistance tend to be more expensive. For example, compared to “polyvinyl chloride”, which is not excellent in heat resistance, “polyimide”, which is plastic with excellent heat resistance, has a unit price in grams. It becomes 100 times.
Plastics with low heat resistance have advantages such as low price and ease of processing.
Price difference by manufacturing method
There are various “manufacturing methods” for plastic products.
Depending on the manufacturing method, the required equipment and equipment will also differ, and the price of the finished plastic product will also vary depending on the manufacturing method and the nature of the plastic product to be manufactured.
For example, “injection molding”, which is a general plastic product manufacturing method, uses a dedicated “mold”, which is quite expensive.
On the other hand, in the case of “blow molding” used in the manufacture of PET bottles, etc., molds are used.
Consider material selection based on manufacturing costs
The appropriate types of plastic products vary depending on what they are used for.
Plastics not only differ in price and heat resistance performance depending on the type, but also have various statuses, so it is desirable to produce plastics with a type that has a status according to the environment used.
However, if only the performance is taken into account, the price may increase, and this requires comprehensive consideration of manufacturing costs and distribution costs.
For example, even plastics with high heat resistance can be procured at a relatively low price, such as “fluorinated ethylene”, so please select a material that clears the required performance and price issues.
