In the die-casting industry, we often encounter a situation where:
For the same product,
quotes from different factories can vary by as much as two or even three times.
Some customers are puzzled:
“Why is there such a big difference in price? Which quote is actually reasonable?”
In reality, the reason behind these price differences isn’t simply a matter of “who’s more expensive and who’s cheaper,”
but rather that each factory has a different understanding of the project, different levels of experience, and different assessments of risk.
1. Differences in Product Understanding
Before providing a quote, some factories carefully assess the following:
Whether the product’s structure is suitable for die casting
Whether there is a risk of entrapped air
Whether the wall thickness is uniform
How difficult subsequent processing will be
If these issues are not thoroughly considered in the early stages,
they may have to be “made up for” later through rework, machine adjustments, or even compromised quality.
In contrast, experienced factories
often factor these considerations into their quotes from the outset.
2、Differences in Materials and Quality Standards
Even for aluminum alloy die-cast parts,
different factories may employ entirely different material strategies:
Proportion of virgin material
Control of recycled material
Whether internal defect inspections are conducted
Whether 100% inspections are performed
These hidden costs
directly impact the final price.
Yet it is precisely these factors
that determine whether a product can be used reliably over the long term.
3、Does the Quote Include the Entire Production Process?
When comparing prices,
many customers often focus solely on the unit price.
However, the details included behind that unit price can vary significantly:
Does it include deburring and grinding?
Does it include CNC finishing?
Does it include surface treatment?
Does it include 100% inspection?
Does it include packaging and shipping?
Some quotes may appear low at first glance,
but additional costs are added at every subsequent step.
As a result, the total project cost ends up being higher.
4、Differences in Yield Rates and Risk Estimates
Die casting is not a process where success is guaranteed simply by producing a part.
Trial mold scrap, fluctuations in yield rates, and structural optimization
can all lead to changes in actual costs.
Experienced factories
often build in a reasonable margin when quoting,
to ensure the project can proceed smoothly.
Some factories, however, may enter a project with a low initial quote,
only to adjust the terms later through various means.
5、Different Order Backgrounds
Sometimes, prices may indeed appear significantly lower.
For example:
Inventory resulting from canceled projects
Factories needing to fill temporary capacity gaps
Reorders for existing projects where mold costs have already been amortized
These situations can all lead to temporarily lower quotes.
However, such prices
often do not serve as a reliable long-term reference.
6、Different Business Philosophies
Some factories place greater emphasis on:
Long-term partnerships
Consistent quality
Healthy cash flow
Sustainable team development
While other factories
prefer to secure orders quickly through low prices.
Different business philosophies
naturally lead to different pricing strategies.
In Closing
A threefold difference in pricing
doesn’t necessarily mean one side is right and the other wrong.
But it certainly indicates:
different underlying assumptions, different experiences, and different assessments of risk.
A truly seasoned procurement professional
doesn’t just compare unit prices,
but conducts a comprehensive evaluation:
Does the manufacturer truly understand the product?
Do they have the capacity for stable delivery?
whether they are willing to take responsibility for quality
and whether they can become a long-term partner
In manufacturing,
price is just the beginning; stability is the end result.
