If you are looking for a China plastic injection molding manufacturer to make your plastic molding parts, your first question was likely How much does the China injection molding cost to make my product? Is there any way to lower the mold cost in China?
The larger the part size is, the larger the mold size is, and needs more mold steel, mold cost will increase significantly.
The more complex part will require a more complex mold structure, which then leads to more mold costs. Reduce needless surfaces and corners or features as much as possible, which will save huge mold costs.
The plastic mold and injection molding parts costs will directly influence whether your project goes smoothly and success or failure. When you start to design a plastic part for injection molding, many factors you should consider, such as part complexity, part size, part surface, part material, mold cavity number, and production volume, will affect the price tremendously.
One cavity mold needs less time and process than multiple cavities mold (also called family mold), which will reduce mold cost, but rise the part unit price. If your production volume is small, then one cavity mold is enough; if the volume is large, you could consider multiple cavities mold.
The material cost will vary according to the type and quality of plastic you use. For example, if you choose high-cost fiberglass filler material, the mold material needs hardened steel, which also will increase the cost.
An attractive surface finish will add more processing cost and time, if the part surface is not very critical or the plastic part is invisible in the assembly product, you can choose a lower-level finish, such as SPI Finish B-3 or lower C grade.
3. How to Reduce the Plastic Injection Molding Cost in China
The best way to reduce the plastic injection molding cost in China is to find a professional plastic injection molding manufacturer. With their help, you don&#;t need to know so many skills to reduce the cost, they will do it for you.
However, finding a reliable plastic part supplier is not an easy thing, you can consider the following tips to reduce your plastic injection molding.
1) Save Cost From the Design
A professional plastic injection mold manufacturer knows well how to control the cost from the design stage. It is a very important skill because the design concept can determine the cost of the whole project.
The plastic injection mold manufacturer usually needs to hold a meeting in the early stage, it should consider the injection molding production, product assembly, and then find the best reasonable design. Engineers will design the mold according to this scheme, which can reduce a lot of costs.
2) One-stop Injection Molding Service
One-stop injection molding service includes mold design and manufacturing, product injection molding processing, plastic shell surface treatment (spray, screen printing, etc.), and other one-stop outsourcing services.
Why do so many plastic injection molding factories emphasize one-stop injection molding services? Because it can not only reduce the plastic injection molding cost but also save a lot of time.
One-stop injection molding service can improve production efficiency greatly. The factory with one-stop service is also very professional and has enough strength to provide you with a better service.
3) Sample Test
A sample test is a must before you start your plastic parts mass production. You should require the injection molding factory to provide the proofing services. This process can tell you whether the molding factory&#;s production quality is good or not.
If the sample quality is poor, the next mass production goods are even worse. To avoid unnecessary loss, a sample test is the first thing you should do before you start your project.
4. Cost Estimating methods for plastic injection molding
Of course, we couldn&#;t totally rely on the plastic injection molding manufacturer to give us the price. We can use some methods to estimate the plastic injection molding cost. Here are some common methods to estimate the plastic mold parts cost.
1) Feature-based cost estimate
This feature-based cost estimation tool is suitable for plastic molding in production quantities (more than 10,000 pieces). Since it has a smaller impact on the cost of each component, more durable and expensive tools can be used. The material costs are estimated based on the geometry of the part, and current material prices are used.
In order to reduce production costs, a compatible injection molding machine was selected from a database of more than 50 machines, and the cycle time was estimated based on the part geometry, material properties, and machine specifications.
For the mold cost, use the standard mold size and mold category to select the appropriate mold base, and estimate the required mold processing based on the geometry of the part and other user specifications. These three costs (materials, production, and molds) are calculated for 4 different cavity arrangements (1, 2, 4, and 8 cavities) and provide the most cost-effective option.
2) Low-volume injection molding cost estimate
This feature-based cost estimation tool is suitable for injection molding in small batches (less than 10,000 units). Because of the great impact on the cost of each part, the rapid tool method (high-speed processing of 104 molds) is used to create molds. Material costs are estimated based on the geometry of the part, and current material prices are used. In order to reduce production costs, a compatible injection molding machine was selected from a database of more than 50 machines, and the cycle time was estimated based on the part geometry, material properties, and machine specifications.

3) Standard estimate
This standard injection molding cost estimator does not require any part geometry but requires more input of process parameters to calculate a more accurate estimate. Material costs are estimated based on the number of parts and runners, and an up-to-date material database containing pricing, and customizable process parameters. For production costs, cycle time, as well as machine rate and labor rate must be specified. After adding mold cost, a detailed cost breakdown of material, production and mold costs is provided.
4) Plastic mold cost estimate
This feature-based cost estimator calculates the mold cost for plastic molding. According to the geometric shape of the part and the requirements of the mold, such as the number of cavities, use the standard mold size to select the appropriate mold base. The required mold processing is for the selected SPI mold type and the rapid plastic mold method can be selected for 104 types of molds or low-volume products.
5. China Plastic Injection Molding Cost FAQ
Here are some problems that our injection mold buyers faced:
1) Is 3d printing cheaper than injection molding?
If mass production is required, traditional molding methods such as injection molding are inseparable. Just need a separate product or sample, try 3D printing.
2) Is a small injection mold cheaper than a large injection mold?
The injection mold price is not only determined by the size of the product, but also according to the complexity of the structure of the product. Small injection mold requires higher accuracy, so the cost of production may be not cheap.
3) How do you know if you have got a good price for your plastic injection molding?
Plastic injection molding is a very competitive industry, there is no standard price at present. To win the customers, some plastic injection molding factories even don&#;t add any profits to the price, only add some processing charges.
Holly plastic has a client who needs a plastic mold for e-cigarettes, before contacting us, they worked with a plastic injection molding supplier in Dongguan. Because using poor material, their mold suction holes are easy to burst.
The price was nearly double that of the first supplier, and it really scared the customer. Because we need to use food-grade material to make this mold, this material will not deform at a temperature of 80 degrees, and it is a special non-toxic material. The client finally agreed to our offer, we finish this project together successfully. So you see, the price is not the only thing we need to consider!
4) Can I choose a small plastic injection molding factory in China as my partner?
In China, especially in Guangdong and Zhejiang, there are many small plastic injection molding factories, some of which can not only give you a great price but also guarantee quality. However, small may not mean cheap, it also means poor quality. Scientific team management can help small plastic mold factories lower the cost and improve the quality, if you find a professional engineering team, a small factory will help you save a lot of money and time.
When it comes to low prices and high quality, China mould supplier and injection molding companies are hard-to-beat. Many foreign customers understand the advantage of sourcing injection molds and plastic molding parts directly from China companies, They also understand that the development of a new product, injection molding process has more benefits than stamping and vacuum thermoforming.
Any mould or plastic parts you purchase can obtain a satisfactory price in China, but don&#;t just care about the price and ignore the other more important, even spent 1 dollar. Do not want to buy garbage back, as a beginner you don&#;t know who are you looking for suppliers, start slowly, spend time learning to explore. You will first focus on several key steps in the process.
Finding a china mold company
Use Google, it offers you a simple, straight-forward channel for locating overseas suppliers, but not all online directories are created equal. But not all the companies you find are what you really need. Cnmoulding advice, through customer understanding and presentation. To ensure that they are legitimate companies and be able to provide the mould and products they claim.GOOGLE is trustworthy in this respect. Some commercial sites. Because of the money collected to determine the company&#;s ranking, allowing vendors to post their own content without any verification.
The second option is to go directly to the plastic mold factory you have chosen to investigate whether they are a real plant, not a prop. Although the cost of such travel requires more effort and higher than the Internet connection, it also provides an opportunity and your injection molding suppliers face to face, to understand the mould company design & manufacturing capacity, their characteristics and strengths, often visit, at the same time enhance each other&#;s feelings.
Selecting and Working with an injection molding company
You can start a small project to test the water, which is responsible for both sides. In order to get the manufacturer&#;s attention, you must show past purchasing records. And show the potential as a long-term business partner. Introduce your company and project, and then ask for a similar material sample and plastic molding sample.
As a professional buyer, you must not only look at the sample. It is more important to check the design drawings and the real injection molds in the factory, to ensure that you see not just a sample. Which can be bought from any market. &#;Select your plastic injection molding supplier have 6 reasons&#; is very helpful for the procurement of the article, we can refer to.
What else should you look for when considering a mould manufacturer in china?
For plastic injection molding products or plastic products. You also need to tell the manufacturer, you need the quality, packaging requirements, gate location, painting position, and so on. Also remember that for the materials you choose, you are legally responsible for ensuring that all products meet the environmental requirements of your country. Find out if your potential supplier has exported molds or injection molding products to the United States, Europe. If so, what kind of export industry, the number of precision, appearance, this will become the basis for your choice. If these companies can provide materials, quality certification is more secure.
Know what you need to design a new product certification, and then tell your potential production plant! Do not buy any plastic products that can not provide proof of material from suppliers, will bring you a lot of trouble. Once you have chosen your Chinese mold manufacturer to deliver your order. It is particularly important to inform the engineer and the mold maker of all the details of the product design, assembly, inspection, etc. The good cooperation between the two sides is directly related to the quality of plastic products, delivery time, and the first T1.
Paying Method
The most common payment terms are 50% advanced, 50% after sample confirm before shipping, Some customer like the way is 30-40-30, although it&#;s less common. Under 30-40-30 terms, the buyer puts 30% down and pays 40% at shipping and the final 30% upon receipt and inspection. But a lot of good mold suppliers don&#;t accept such payment methods, it is important you should remember, mold company is your assistant.
Quality Control
If you buy injection molds, you check the mold quality in two ways: trust the supplier, small batch production inspection. In a small order, you can choose to trust the vendor. It should be noted that prior to mold manufacturing, mold design drawings must be confirmed, including the gate position, ejector pin Location Flow Chart, mold size, cooling design, the standard joints, hot runner Location Flow Chart design,
If you buy a large mold, you can choose to produce - set products in an injection molds company. So that the mold to the best state and then exported. If you purchase plastic injection products, you can consider hiring an employee to help you check the product in China. Do not consider hiring a third-party inspection company, good cooperation will destroy by rigorous inspection methods between customers and suppliers.
Shipping and Logistics
For samples and small batches, high-value products, and the express couriers may make sense &#; because hungry they need quick service. Airfreight is proving to be the most effective option for shipping relatively small orders or important goods. Large quantities of goods shipped by sea ships can take up to 15 days or more. (not including clearance time) but the air transport cost is savings (especially larger orders) can be substantial. Our article is base on our previous customer experience, can replace the lesson, save your cost.
