Type: precision molding
This example of the Lego part shows how to achieve the precision of the injection mold final plastic part. Click to see more details.
Type: precision molding
An injection mold for producing a power tool housing. This example shows the importance of proper gate design. Click to see more.
Type: clear plastic molding
These are lenses for LED lights. The surface pattern is most critical for the proper projecting of lights. Each part need to have the same weight for cost saving in large volume production.
Type: precision molding
This is a pin connector used on PCBs. High precision and uniformity are required.
Type: precision molding / TPU molding
This is a side seal for mobile phones, with the material TPU. There are small details made to high precision to prevent flashes.
Type: TPE overmolding
This is a handle for power tools. The substrate is ABS with TPE overmolded.
Type: chrome plating
This is a wide reflective mirror made of ABS, with the surface plated with chrome.
Type: ultrasonic welding
The cup body consists of 2 walls for better heat insulation. The bottom is welded to the cup body. The material for this cup is ABS.
Having properly defined quality standards is delicate, and we will provide our insights in this area to make your project a success.
1. Understand the product
Providing details about the product’s use, how plastic parts are assembled and function in the assembly can help us understand the dimensional and aesthetical requirements.
2. Set the inspection criteria
We will create a 2D drawing, specify all necessary dimensional and geometric tolerances (such as flatness, roundness and concentricity), and define the amount of acceptable bending, warping and distortion.
3. DFM and Mold Flow Analysis
We will conduct a DFM and probably a mold flow analysis to see what issues may arise either on the product side or the mold side. Some issues need attention from the mold design stage.
Many molding defects are predictable, and they can be avoided or kept within an acceptable level.
Our engineering services
Choosing the right material is crucial to the success of a project from the very beginning。
We don't usually start from scratch, because communication from a distance can be a barrier. We can optimize your design in terms of manufacturability, aestietics, and functionality.
In addition to using professional scanning and measuring instruments, it takes experience and talent to replicate a product exactly as the original sample.
Other than photosensitive resins, we can use different materials for rapid prototyping: soft/flexible, transparent, and nylon.
We always base our low prices on sufficient quality for their purposes.
We keep our price low and transparent. If you request, we will send you mold cost breakdown so you can see the composition of the mold cost, and you can also check each item is reasonably and correctly calculated.
The below table gives the usual percentage of each cost:
The processes of mold making
The DFM and Mold flow analysis can help you avoid potential production problems, optimize the part and mold design and shorten the overall production cycle.
This will include deciding the type and location of the injection gates and ejector pins, wall thickness and draft analysis, possible molding defects and solutions, and so forth.
— At Boyan, we are always grateful for the opportunities to face challenges, inspire creativity, and grow alongside our customers’ businesses.
Customer references are available in these countries. If you would like to speak with our customers directly, we can provide you with their phone numbers.
Frequently Asked Questions
Do you Provide any kind of Warranty ?
If you find the injection molded parts do not meet the specs or have any quality issues within 3 months of their arrival date, please inform us with pictures indicating those issues. We will send you free replacements at our cost, including possible air freight charges.
What is your MOQ for orders?
There is no MOQ required from us, we take orders from 100 units to 1 million, however, the injection mold itself is kind of expensive. To make your investment worthwhile, we suggest your order quantity should be more than 100, otherwise, you should consider other manufacturing processes.
How do I know I will get the products as I expected?
We will analyze what molding defects may arise before mold production, and take preventive measures.
We will send you detailed QC reports with pictures and videos during production and before shipment, so you know exactly what you will receive prior to shipment.
What is the typical mold life?
A mold can complete from 10,000 shots to 1 million shots, we will choose what mold steel to be used based on your estimation of the quantity. At the same time, if you let us produce the plastic parts, you do not need to worry about the mold life, we will take care of the mold maintenance and renewal, so it is a one-off investment for you.
How do I describe the quality requirements for my products?
It is important that you describe the quality requirements clearly, including the material specs, dimensional tolerances, and visual requirements. If you do not have an engineering background, you can explain to us the application in detail. We will figure it out and list the requirements and specs on a pdf drawing for review. It will be used in manufacturing and QC inspection.
