(6) Mold HS code and Export Tex Rebate Rate.
HS code#8480410010
For injection mold or die casting mold for automobiles and household appliances
HS code#8480410090
For injection mold or die casting mold for metals and hard metals
Tex Rebate Rate is 11% in China for plastic injection mould
(7) Are there any competitive/alternative products on the market?
Mold is the mother of the modern industry. At present, there are no alternatives for massive production because of its high efficiency and precision.
Today’s 3D printing technology still can not solve the high-precision requirements, and the ability is also relatively low, so only a few products with low precision requirements are suitable to replace mold production with 3D printing.
(8) Name the area where the mold are widely used
USA, Canada, Germany, France, UK, Italy, Netherlands, Spain, Switzerland, Portugal, Czech Republic, Slovakia, Slovenia, Poland, Romania, Japan, South Korea, China, etc.
Mainly in industrial developed countries and areas, there is more demand for various kinds of mold, including mold for automobiles, home appliances, medical treatment, electronics, office supplies, packaging, aerospace, etc.
In other industries less developed areas, only mold such as household and daily necessities are generally needed, such as mold for the production of spoons and plates, fruit basket, flower basket, storage box, and so on.
(9) The approximate size of the mold that Five-Star produces
Five-Star Tooling produce small mold, the weight of dozens of kilograms, size of about 150*200*250(mm), or several hundreds kgs to 3tons, size of 1000*600*600(mm); medium mold, 3ts to 10ts, size of 1500*1100*800(mm), large mold from 10t to about 50t, size of 5000*4000*2500(mm) and super large mold of over 50t to 100t.
(10) What’s the price of mold materials?
From 8RMB per kg to 800RMB per kg, the price varies from different materials. Like regular S50C, it takes 8RMB per kg while 25 RMB/kg for China Aluminum, 70RMB/kg for imported Aluminum, 25RMB/kg for 1.2738, 55RMB/kg for 1.2344, 60RMB/kg for 1.2714, 160RMB/kg for S136, 550RMB for M390, 580RMB/kg for Ampco, 780RMB/kg for 780, based on the exchange rate of 6.5 USD/RMB and 7.5 Euro/RMB. ( 2021 data for reference)
(11) Which factors would directly affect mold cost and its price?
Type of materials, brand of hot runner, cylinder, standard components(original or China), and requirements on tolerance and delivery time. Usually the shorter the delivery time, the higher the mold price would be.
(12) Which procedures are produced in house and which are not?
We only outsource heat treatment and surface treatment and do the rest of the procedures ourselves.
(13) Who are your main customers? Importers? Project business? Or Brands?
Importers, injection molding plants, die-casting plants, stamping plants, as well as some product production, assembly plants. For example, Ford, Tesla, BMW, Electrolux, Airbus, etc.
Don’t do necessary output by themselves. They have their supporting suppliers to produce the products and deliver them to them after assembly.
(14) What product related problems do customers often complain about?
a) Slow design
b) Long time for drawing confirmation
c) Processing error
d) Processing delay
e) Late time for mold test
f) Or unqualified T1 mold test sample, like problems such as flash, trapped gas, ejector mark, deformation, size out of tolerance, etc.
g) As well as long time for mold engineering change
h) Delayed shipment, etc.
(15) Where is the industrial concentration of the industry? What is the nearest shipping port to the industrial focus?
It is concentrated in Jiangsu, Zhejiang, and the Pearl River Delta in China.
The nearest shipping ports are Yantian port, Shekou port, Hong Kong port, Chiwan Port, Guangzhou port, Wenzhou port, Ningbo port, Shanghai port, Taicang port, Lianyungang port, Shekou port, Chiwan Port, Hong Kong port, etc.
(16)How long is the production cycle of the mold produced in Five-Star? Which kind of mold takes the shortest and the longest? Why?
2-15 weeks, depending on the complexity of the mold and the size of the mold.
Generally, small mold with simple structure take 2-5 weeks, the medium complex structure takes 5-8 weeks, while more than 8 weeks for complex structure.
Conclusion
Generally speaking, to be familiar with a product is nothing more than the following aspects: raw materials, manufacturing process, cost, performance, output, specification and packaging, price, purpose, final use place, and the possibility of secondary development.
