Over Molds

China has become a major destination for Plastic Injection Mold and molding parts service. Lower prices are the primary incentives for many foreign buyers. The majority of foreign buyers find challenges sourcing plastic injection molding from China. The major strains are on how to buy, how to evaluate quality, or how to identify a reliable source.

Many things go wrong in case of compromise in the purchase process. For example, delayed delivery, frauds, low quality, weakness of communication (both on language and technical), and other problems may be encountered. To avoid such frustrations, the following is a process of how a buyer would purchase plastic injection molding from China. Hope this could help you find your best suitable supplier

Identify a Reliable Plastic Molding Manufacturer

Currently, there are many mold manufacturing companies in China. You need to determine which supplier is reliable. Some of the factors to consider include, mold price, quality, quantity, accessory standard, communication, lead times, and the mold design, among other factors.
Using the World Wide Web, you can easily find a wide range of plastic molding suppliers from the internet, sourcing agents, and trade shows, etc.

It is important to contact several suppliers before making a decision on a suitable supplier.
Buy Plastic Injection molding from China

Evaluate the Various Mold/Molding Manufacturers

Conducting market research on the various plastic molding manufacturers helps to find a suitable fit for the business. So how can one evaluate the Chinese mold makers to identify a reliable source?
Sending inquiries helps the evaluation process. You should focus on asking questions that evaluate the core competence of the plastic molding companies.
A good supplier is one that shows interest in your projects, has effective communication, knowledgeable, detail-minded, and honest. The evaluation should target to identify the salient attributes of the supplier, for example, what is advantages do they have, is it suitable for your project? Have they done any similar projects like yours? All of the information will help to make your project smoothly or not.

Information Verification

Not all manufacturers are who they say they are. The customer should be able to verify the plastic molding manufacturer. Some of the information that can be verified include:

  • Type of mold parting line
  • The type of ejection modes, whether pins are used and the particular locations,
  • Surface requirement on the visible surface
  • The location and type of gates

Such information helps to verify the mold designs and product appearance. the most important thing is basing on this discussing with each other you will know their communication and technology ability. A supplier that verifies the information and offers samples is reliable.

Analysis of Production Issues that may Arise

A good plastic molding supplier should communicate the issues in advance and concerns that may arise in the production process, and actions are taken to address the issue. A good injection mold company should analyze the current design and offer rational recommendations, we call this DFM report.
Some of the important questions that help identify some of the issues include;

  • Have you produced similar molds/products before?
  • What were the challenges encountered?
  • Can you send your quality control inspection report?
  • How do you address the issues that arise?
  • Do you offer compensation for compromises?

With all the information, you should already have identified which Chinese molding company to source from.

Firm/Supplier Site Visit 

Depending on the quantity of supply sourced, visiting the supplier may be important. For large quantities of plastic molding service, traveling to China should be a basic step. The objective is to analyze samples and evaluate the reliability of the supplier.

Go to their plastic molding company on site to communicate with them face to face, then you will know how the technical skill, English ability, etc.  But mostly not always have time to check their mold factory, so we suggest you may ask for a skype video shows if you have no time to visit them.

At SINCERE TECH will take Skype video meeting to show you around our plastic mold and molding factory if you have no time to visit our factory, our sales and project manager speak good English and have the professional technical skill, you will know this during the video shows. if you are interested in our service, you are welcome to contact us.

Importing products from China and Asian nations can be risky and complicated. Contracts are antidotes against the common mistakes and issues that may arise. It is essential for buyers to get into a contract for the following reasons;

  • To maintain clarity on product specifications and avoid misunderstandings. The specifications of the product can be easily lost in Skype or mail communication.
  • Compensation terms help suppliers to think twice about compromise.
  • Contracts help to communicate on how severe your business is
  • It helps to avoid delays

The first time you work with a China plastic injection molding company (same to work with your local supplier), you should always make agreements on contracts to avoid scams and fraud. Suppliers who default the negotiations should be responsible for making refunds and necessary compensations.

7.Payment and Delivery

Based on the set agreement, the amount can be paid by one time or two times ( maybe more times). The payment method depends on the agreed strategy. Some companies make payments via Paypal, Skrill, Payoneer, Western Union, Cheque, or other policies. Our standard payment term is T/T wire transfer. If the small amount. PayPal is still available,  this is method is normally working for all of the companies in China, especially for custom plastic molding manufacturing service.

Compare the superiority of major mould manufacturing countries

The world’s major mold manufacturing countries, including the Asian region: Japan, South Korea and mainland China, as well as the United States & Germany, this article will induce different countries in mold industry and comparative analysis of national competitiveness and the strength of our differences.

1, mold industrial status in different countries

Countries in the world’s major manufacturing and marketing area, China has the largest number of plastic mold companies, nearly seven times as state-owned enterprises, foreign-funded enterprises account to run the large-scale mold factory and employs approximately 600 ~ 700 people, Foxconn Hon Hai Group (Foxconn) employs nearly 6,00000 people, mold factory is between 150 to 300, small mold factory about 50 people, other countries mold industry have much more small factories, Applications market, Japan, South Korea, the United States and Germany produce the largest proportion for automobile products, while China produces electronics and communications products and mold.

In accordance with 2002 national research report, Japan, South Korea and Germany, mold is a strong quasi-surplus goods, the China mainland and the United States mold due to domestic demand in large markets and are unable to complete the supply of domestic firms and required by the import of mold in order to meet downstream market of products manufacturing, , import and export of the region are mostly in neighboring countries, while Japan exported more remarkable region in the U.S. mainly, but mainland China in recent years due to the rapid development of downstream industries, mainland China has been gradually turned to expanding market trends

Wage countries, according to 2002 white paper on the findings of the mold industry, Germany paid the highest salaries of technical staff for $ 12.13 ~ $ 19.28 per hour, the designer is $ 16.91 ~ $ 25.26, between Japan and the United States, the mold factory pay the lowest-paid technicians annual salary of only $ 732 ~ $ 5,853, the designer is only $ 2,927 ~ $ 5,853, China low wage costs have so great advantage

2, analysis of national strengths and weaknesses Technologically advanced countries such as Japan, the United States, Germany, for high-precision and complex nature of mold development, regardless of design capacity or manufacturing technology, have a leading position, but also have excellent R & D personnel practice. The Japanese mould maker emphasis on technically polished with the polishing process, the German mold manufacturers by enhancing mechanical processing and electrical discharge machining precision and efficiency begin to reduce the manual processing time. Market size regardless of value or domestic demand in Japan’s decline was most evident. Operating costs are often faced with high wages, high benefits, so the downstream industries or mold makers to move production facilities to gradually close to the newly industrialized countries or technological backward countries, in order to reduce labour costs and enhance price competitiveness, but the trend is likely to cause technical invisible exodus worries, making themselves, even more, to be put in a large research and development costs in order to speed up the upgrading process technology and high-speed mechanical properties, widening the difference between each other. Taiwan, Korea and mainland China, South Korea and mainland China market in recent years, the scale of production and demand are presented growing trend, particularly in mainland China mould industry is the rapid development of national brand name manufacturers stationed in production equipment, invisible mold development to enhance the strength and design capabilities. Costs, mainland China and South Korea because it has a relatively low labour cost advantage, and therefore the selling price for the mold, often take low-cost marketing to market, and thus poor global economic situation, the successful buyer to grab the market favour, the most obvious example of the gains in export value.

3, the conclusion On the whole, as countries mould industry, and many types of small business operations, therefore, operating on a regular fund-raising is difficulty, in the absence of government policy support and tax incentives in the formation of mold industry will go it alone with the situation alone, the only way is increasing the additional value of products in order to get rid of low-cost competition.
