The quality of the stamping parts depends on the factors
6. Finish
The surface treatment of continuous die metal stamping is different from that of transfer die metal stamping.
After heat treatment, the surface of high-quality continuous die stamping will be coated with antirust oil or black oxide. However, if your product needs a higher aesthetic, consider having it polished by an experienced worker.
Surface treatment significantly improves the quality and performance of metal stamping.
7 Process
Continuous die metal stamping parts are usually transferred to the machining department after stamping.
High quality continuous die stamping parts may have to go through a series of locomotive cutting and other processes to complete the finished product. Each is essential to ensure a high quality product with precision, smooth surfaces, beautiful appearance and enhanced performance.
8. Parts inspection
When choosing a professional Chinese metal stamping manufacturer, it is necessary to check whether they have the required equipment, such as coordinate measuring machines (CMM) and ultrasonic detection (UT), to ensure product quality.
It is best to choose a manufacturer with an in-house laboratory that can perform hardness tests on molds and finished products once a week. This helps you avoid some unexpected problems after stamping manufacturing.
There are two types of inspection in the metal stamping industry, 1) random inspection, carried out by the machine operator during the manufacturing process, and 2) final 100 percent inspection before packaging, which can only be done by highly qualified workers.
9. Delivery date
In order to meet the urgent demand, many metal stamping manufacturers can not deliver a large number of parts on time because of the difference in production workload.
When you need high quality stamping parts, ask your supplier about their capacity and how long it will take to produce the product after you place your order. If they tell you that they will provide a quote within 24 hours of your inquiry, the supplier can be considered a specialist supplier.
10. Mark and paint
Marking and painting are key processes to make your final product look its best by brand name, model number, and/or other descriptive information.
High quality metal die is equipped with advanced 3D laser marking equipment, which can provide accurate marking and high machining speed. These are automated machines that reduce the labor costs of these procedures.
However, they are also expensive compared to traditional marking methods, so be careful when choosing a manufacturer.
11. Quality control process
Quality control is always one of the most important factors in determining whether your stamping parts meet customer requirements.
High quality manufacturers should have quality control personnel responsible for testing their products in every procedure, including heat treatment.
Their testing procedures should be strictly defined in accordance with international or national specifications, which you need to provide prior to production. If possible, consider ISO system certification to ensure that all your programs are controlled by qualified management personnel.
12. Packing and shipping
Proper packaging and transportation can reduce the risk of damage to stamped parts, especially large and/or heavy parts.
Consult your stamping manufacturer for details about their packaging and shipping options prior to production. Also, if possible, please provide samples of similar products and test packaging and shipping.
13. Price
Price is a factor you can't ignore when choosing a metal stamping manufacturer, but that doesn't mean the lowest price is the best choice.
Quality and service levels are a function of price, so don't make the mistake of making a choice based solely on cost. Compare prices and service levels before choosing.
14. Profit Margin
Margins are something few people discuss, but they are an important factor. Before deciding which hardware stamping manufacturer to choose, consider your final profit margin and determine if the price being offered will allow you to earn the profit margin you need.
If not, you will consider lower production costs or even higher productivity from a high quality hardware stamping manufacturer.
15. Reliability
The best way to determine reliability is through feedback (word of mouth) from other businesses that use their services. You can also take advantage of trade platforms that provide vendor evaluations for its members.
16. After-sales service
You must pay attention to the after-sales service provided by the stamping manufacturer of your choice. If there is a problem with your product, the manufacturer should immediately provide after-sales service according to your request, including remanufacturing and repair.
A professional metal factory should have a machine maintenance department and spare parts store in case of any unexpected situation during production. Even if it takes longer, they should stay in close contact with you.
If you find that your hardware stamping manufacturer only provides tool repairs without spare parts, then they will not be able to provide after-sales service for your product.
