Injection Molding
We specialize in high-quality plastic injection molding, supporting projects from low-volume prototypes to high-volume production with consistent precision and reliability.
Over Molding
A specialized injection molding process where a second material ( TPE, silicone, or rubber) is molded over a rigid substrate (plastic or metal), creating a seamless, multi-material component.
Insert Molding
A specialized injection molding process where pre-fabricated metal or plastic inserts are placed into the mold, then encapsulated with molten material to form a single, robust composite part.

Frequently Used Plastic Material and Examples
ABS
Created using a specialized emulsion, Acrylonitrile Butadiene Styrene (ABS) is a cost-effective thermoplastic with high resistance to corrosion and low melting temperature.
Nylon
Nylon material is sturdy and wear-resistant, and it is often used in the automotive, electronics, machinery, and aviation fields.
POM
Polyoxymethylene (POM) has high hardness, strength and rigidity , good self-lubrication and good fatigue resistance in a wide range of temperature and humidity. POM is widely used as sliding and rotating mechanical parts, gears, levers etc.
PMMA
Acrylic is comparable to polycarbonate in terms of properties yet available at a lower cost. This transparent polymer is also ideal for multiple projects for its tensile and flexural strength.
PE
Made from petroleum, High-Density Polyethylene (HDPE) boasts high tensile strength and impact resistance marks while also having a high melting point.
PP
Being food-grade, polypropylene can be applied for consumer goods and medical products due to its sanitary properties.
TPE
TPE soft rubber has the high elasticity of rubber and is often used in toys, daily necessities, sports protective gear, and electronic products.
TPU
Thermoplastic polyurethane (TPU) has elastic and excellent resistance to oil and grease that makes them ideal materials for the field.
PC
Polycarbonate is a solid and durable injection molding material commonly used for electrical and automotive components.

How to Work
From the moment your injection mold order is confirmed, we follow a standardized procedure to ensure transparency and smooth transitions at every step. This process keeps both our team and customers fully informed on the progress, guaranteeing that each phase is executed efficiently. Here’s how we begin and complete your injection mold project:
1
Confirm drawings, materials, and requirements. Once the quotation is approved, we sign the order and start the project.
2
We conduct DFM analysis and complete mold design. After client approval, we proceed to mold fabrication.
3
We carry out steel machining, CNC, EDM, polishing, and mold assembly, progressing each step on schedule.
4
We carry out the first mold trial (T1) to verify dimensions and appearance, and provide samples with a trial report. Multiple iterations (T2/T3) are performed as needed until the sample meets all requirements.
5
We make necessary adjustments based on trial feedback, ensuring the sample meets all requirements. Once quality inspections are passed, we provide the client with the final confirmation before proceeding to mass production.
6
After receiving final approval, we start mass production, ensuring consistency in quality and maintaining production schedules. Each batch is carefully monitored to meet client specifications, with regular progress checks to ensure no delays.
7
During and after production, we perform rigorous quality control checks to ensure that all products meet the highest standards. Any defects or issues are immediately addressed and resolved before products are approved for shipment.
8
Once quality inspection is completed and the products are approved, we package the products securely to prevent any damage during transportation. We arrange for timely shipping according to the client’s specifications and preferences.
9
We offer a lifetime warranty for injection molds used in-house. We are committed to maintaining consistent quality.

Plastic Injection Molding FAQs
Q1: What is plastic injection molding?
Plastic injection molding mass-produces precision plastic parts by injecting molten material into molds, where it cools into finished components. The process ensures consistent, high-volume output with tight tolerances.
Q2: What type of plastic material is best for my design/component?
Your product's requirements dictate material choice – our experts match plastics to your needs, then verify through trial molds to ensure perfect fit for form, function and quality.
Q3: How can I get a Quotation?
- 3D CAD files (STEP/IGS/X_T)
- 2D drawings with specs (tolerances/material/surface)
- Projected volumes (MOQ/annual forecast)
Q4: Is it possible to know the operation status of my products without visiting your company?
Our team delivers detailed production schedules with weekly visual reports (photos/videos) to keep you informed of machining progress.
Q5: What is your MOQ?
No minimum order quantity required – higher volumes mean better pricing. Feel free to place trial orders to evaluate our quality and service firsthand.
Q6: How do you guarantee the quality of mass production?
Our rigorous quality control guarantees uniform excellence: Approved mold samples become your production benchmark. Throughout mass production, specialized QC teams conduct inspections every two hours while strictly following approved specs. Before shipment, we implement AQL random sampling and full inspections to ensure quality compliance at every production phase.
Q7: How do you provide after - sales service?
We offer a 2-year warranty service starting from mold delivery. Should any mold components get damaged during this period, we will provide free replacement parts to ensure continuous production.
