Injection Molding Part Surface Finishes
PTSMAKE offers a wide range of high-quality surface finishes for injection molded parts. Below are some of the most common options, but we also provide additional custom finishes tailored to your specific needs.
MoldTech Finishes (Mold Texturing): We offer a variety of textured finishes, such as matte, swirl, line, and pattern effects. Common MoldTech options include MT11010, MT11020, and MT11030. Additional textures can be requested.
Standard Finish: This is the moldmaker’s default choice, typically following SPI B-2 standards. The finish is determined by the mold’s geometry and draft angles, with interior, non-visible areas often left with as-machined finishes.
SPI Finishes: A range of Society of Plastics Industry (SPI) finishes is available, from Grade 3 diamond polish to a 320 stone low polish. Options include SPI A-1, A-2, A-3, B-1, B-2, B-3, C-1, C-2, C-3, D-1, D-2, and D-3.
Other Textures – VDI: The VDI 3400 surface finish is based on a German engineering standard (VDI) and is typically achieved through EDM machining. It offers a range from fine to coarse matte finishes.
As Molded: This finish involves no additional polishing or grinding. The part will display tooling marks from the molding process.
Threaded Inserts: We install a wide variety of standard threaded inserts in both UNF and metric sizes, accommodating your project’s needs.
Pad Printing: We provide pad printing services to transfer 2D images onto 3D parts. All images are reviewed before transfer.

Cost and Quotation
We believe in transparency and clear communication with our clients. Our cost structure is carefully designed to balance quality and affordability, while our delivery lead times are optimized to ensure we meet your business requirements. Below, we provide a detailed breakdown of how we manage costs and delivery for our injection molding products.
Raw Material Costs
Raw materials are a major part of the manufacturing cost for injection-molded products. We source a wide range of high-quality materials, including various types of plastic resins like ABS, PC, PP, PE, and PVC, as well as additives and pigments. The choice of material depends on your product’s functional needs and appearance, such as strength, flexibility, heat resistance, or look.
- Material Sourcing: We work with trusted suppliers to ensure consistent quality and competitive pricing.
- Material Type & Grade: Different material grades affect the performance and cost of your product. High-performance engineering plastics may cost more than standard materials.
- Material Waste: We strive to minimize waste during production to reduce costs and environmental impact. This helps us pass savings on to you.
Mold Costs
Manufacturing custom injection molds is essential for injection molding. Mold costs are one-time fees that vary based on the product’s complexity and the number of cavities in the mold.
- Mold Design & Prototyping: The design and prototyping stage is crucial in ensuring that your mold will produce the desired part quality and quantity. We work with you to refine the design and reduce costly changes later in production.
- Mold Material: The material used for making the mold (such as steel, aluminum, or alloy) directly impacts the mold cost. Steel molds are more durable and suited for high-volume production, while aluminum molds are typically less expensive but suitable for lower-volume runs.
- Mold Life & Maintenance: Molds can run last for hundreds of thousands of cycles, but regular maintenance may be required to maintain their performance, especially for high-precision molds. We ensure that molds are built to last and are properly maintained to avoid unplanned downtime during production.
Production and Processing Costs
Production costs are determined by the complexity of the injection molding process, the efficiency of the equipment, and the required post-processing steps (such as assembly or finishing).
- Cycle Time: The cycle time for each injection cycle depends on the material, part size, and complexity of the design. More intricate parts may take longer to molding, which affects the overall cost of production.
- Tooling & Setup: Setting up machines, adjusting molds, and running test batches all take time and are factored into the production cost. For high-volume orders, we can optimize production schedules to minimize setup time and reduce costs.
- Post-Processing: Many injection molded products require secondary processes such as trimming, polishing, painting, or assembling. These additional steps are factored into the overall cost.
Labor Costs
Skilled labor is essential in injection molding. This includes machine operators, mold setup technicians, quality inspectors, and assembly staff. Labor costs can vary depending on production volume and the skill levels required.
- Skilled Workforce: Our team is highly trained in operating advanced injection molding machines and ensuring quality control throughout the process.
- Quality Assurance: Labor costs are also affected by the number of quality checks required to meet strict customer specifications.
Shipping and Logistics Costs
Shipping costs depend on the order’s destination, volume, weight, and the chosen shipping method. We offer a variety of shipping options to help you manage costs and ensure timely delivery.
- International Freight: We coordinate sea freight, air freight, and express courier services depending on the urgency of your order. Sea freight is typically more cost-effective for larger shipments, while air freight is faster but more expensive.
- Customs Duties & Taxes: Import duties, taxes, and customs clearance fees vary by country and region. We can provide assistance in calculating these costs to ensure there are no surprises.
- Packaging: We ensure that all products are securely packaged to prevent damage during transit. The cost of packaging is included in the shipping costs.
Custom Plastic Injection Molding Project Lead Time
We understand the importance of on-time delivery and work hard to ensure that our production schedules align with your business needs. Our delivery lead times vary depending on order specifics, product complexity, and shipping method.
Analysis Your Design
Our technical manager will review your design, helping you develop and assess new products faster, more cost-effectively, and with reduced risk, ultimately lowering your overall costs.
This process typically takes 1 to 5 days.
Mold Manufacturing
Once the mold design is approved, we create the mold and conduct trial runs to ensure that the product meets your specifications. This phase can take additional time depending on the complexity of the design and required adjustments.
Production Runs
Once the mold is created, we will produce a sample for your approval. Production will only begin once the sample meets your expectations. 1-15 days after sample and mold approval, depending on order size.
Shipping Time
The shipping time depends on the chosen shipping method and destination: Sea Freight: Typically takes 4-6 weeks, depending on the destination port and customs processing time. Air Freight: Generally takes 5-7 days, but this option is more expensive.

How Does Plastic Injection Molding Work?
1. Mold Desig & Manufacturing
We design and manufacture precise molds to ensure the shape and details of the products.
2. Plastic Material Preparation
Select high-quality plastic pellets and dry them to ensure molding quality.
3. Injection Parameter Debug
Adjust machine parameters, such as temperature and pressure, to suit different product requirements.
4. Injection

5. Cooling and Solidification
Plastic cools and solidifies in the mold, forming the final shape and ensuring dimensional stability.
6. Ejection and Take Out
After cooling, the mold opens, and mechanical devices eject and remove the finished product.
7. Post-Processing
Perform surface treatments to ensure the product is smooth and aesthetically pleasing.
8. Inspection and Packaging
Strictly inspect product quality, ensure no defects, then package and prepare for shipment.
