Injection molding is a mass-production manufacturing process that injects molten material (usually plastic) under high pressure into a precision-machined mold, where it cools and solidifies into identical parts, ideal for high volumes due to low per-part cost, though it requires a high upfront investment for tooling (molds).
How it works
Material: Plastic pellets (resin) are fed into a heated barrel.
Melting & Injection: A screw mixes and melts the plastic, then pushes it under pressure through a nozzle into a closed mold cavity.
Cooling & Ejection: The plastic cools and hardens to the mold's shape, often assisted by cooling channels.
Repeat: The mold opens, the part is ejected, and the cycle repeats.
What it makes
Almost any plastic part: bottle caps, car parts, electronic housings, medical devices, combs, etc..
Components ranging from tiny to large body panels.
This versatile technique creates complex shapes with tight tolerances for industries from automotive to consumer goods, using materials like thermoplastics, and results in strong, repeatable parts with little waste, often ready for use immediately.

When to use it
Shipping way:
1) 0-100kg: express&air freight priority,
Q1: What types of plastic molding processes do you offer?
A: We specialize primarily in Injection Molding, which is ideal for high-volume, complex, and precise parts. Within this, we offer:
Standard Injection Molding
Insert Molding (for combining plastic with metal/other inserts)
Overmolding/Two-Shot Molding (for multi-material or soft-grip parts)
Micro-Molding (for very small, high-precision components)
We also support related processes like Ultrasonic Welding and In-Mold Decoration.
Q2: What file format do you need for a quotation?
A: We require 3D CAD files for an accurate quote and DFM analysis. Preferred formats are STEP (.stp), IGES (.igs), or Parasolid (.x_t). 2D drawings (.pdf, .dwg) are also helpful for specifying critical dimensions, tolerances, and finish requirements. Please ensure your files are in 1:1 scale.
Q3: What are your standard tolerances for plastic parts?
A: Standard tolerances follow ISO 20457 (Plastics - Tolerances for molded parts). For most common thermoplastics:
Linear Dimensions: Typically ±0.1% to ±0.3% of the dimension, with a minimum of ±0.1mm.
Critical Fit Dimensions: Can be held to ±0.05mm with proper mold design and process control.
Specific tolerances depend on part geometry, material, and mold design. Our DFM report will provide detailed recommendations.
Q4: Can you work with engineering-grade or high-performance plastics (like PEEK, PEI)?
A: Yes, absolutely. We have extensive experience processing a wide range of materials, including:
Engineering Plastics: Nylon (PA6, PA66), PC, POM, PBT, PET.
High-Performance Plastics: PEEK, PEI (Ultem), PSU, LCP. These require specialized molding machines with precise temperature control.
We will advise on the best material for your application based on mechanical, thermal, chemical, and cost requirements.
Q5: Who owns the mold?
A: Standard practice is that the customer pays for and owns the mold. We store and maintain it at our facility at no charge during our production contract. We provide regular maintenance and condition reports. Upon project completion, the mold can be shipped to you.
Q6: What is your Minimum Order Quantity (MOQ)?
A: For injection molding, the MOQ is primarily driven by mold amortization. Our typical production MOQ is 10,000 pieces. However, for simpler parts or strategic partnerships, we can be flexible. For prototype/low-volume runs using existing or shared tooling, MOQs can be as low as 500-1,000 pieces.
Q14: What is your typical lead time from order to shipment?
A: Lead time depends on the project stage:
New Project (Requiring Mold):
Mold Manufacturing: 4-8 weeks
First Samples (T1): +1-2 weeks after mold completion
Mass Production: +4-8 weeks (based on quantity)
Repeat Order (Existing Mold): 4-6 weeks for production and shipping.
Q7: What are your payment terms?
A: Standard terms for new customers:
Mold/Tooling: 50% deposit with order, 50% balance before sample shipment.
Production Orders: 30% deposit with order, 70% balance before shipment.
For established customers, we offer more flexible terms (e.g., net 30).
Q8: What happens if there is a quality issue with the parts after delivery?
A: We have a strict quality guarantee. Please notify us immediately (within 7 days of receipt) with photos and details. Our quality team will conduct a root cause analysis. If a manufacturing defect is confirmed, we will arrange for replacements, rework, or credit. Proper storage conditions by the customer are assumed.
If there's anything we can help, please feel free to contact us.
