Services

PTMS provides precision plastic injection molding services for companies that need reliable production, practical engineering support, and stable long-term cooperation. We work with customers across automotive, electronics, medical, consumer goods, and industrial sectors to deliver many different custom injection molded parts that meet functional, dimensional, and quality requirements.

Beyond our company background, PTMS also supports each project with practical engineering, flexible production, and reliable quality control. From early-stage concept review to finished parts delivery, we help customers move forward with confidence at every step of the process.

Every successful project begins with proper design evaluation. Our engineering team carefully reviews part structure, wall thickness, draft angles, material selection, and assembly requirements before mold making begins. This helps improve manufacturability, reduce development risk, and avoid unnecessary changes later in production.

We also assist customers who only have sketches or rough concepts. In many cases, we can help turn an initial idea into a workable design, then support mold making and parts mass production through the full project cycle.

PTMS is equipped to handle both simple and complex injection molding projects with a strong focus on accuracy and repeatability. Our production capabilities support prototype development, small batch orders, and high-volume manufacturing, depending on the needs of each customer.

Our facility uses advanced injection molding technology, automation support, and process monitoring systems to help maintain consistency throughout production. For injection parts with demanding tolerances or special structural requirements, we apply careful process control to achieve stable results.

Different products require different materials and injection molding methods. That is why we support a wide range of thermoplastic materials and advanced processing solutions to match the application, appearance, and performance goals of each project.

Common Material Options

Different products require different materials and molding methods. That is why we support a wide range of thermoplastic materials and advanced processing solutions to match the application, appearance, and performance goals of each project.

Option	Typical Use	Main Benefit	Best For
ABS	Electronics housings, consumer parts	Good impact resistance and easy processing	General-purpose molded parts
PC	Medical devices, transparent parts	High transparency and strong durability	Parts that need clarity and strength
PA6/66	Automotive and industrial parts	Good wear resistance and mechanical strength	Functional parts under stress
PEEK	Aerospace, high-temperature applications	Excellent heat and chemical resistance	High-performance demanding parts
TPE	Soft-touch consumer products	Flexible and comfortable feel	Grip parts, seals, and soft components

Advanced Molding Processes

Our capabilities include overmolding, insert molding, and micro-molding for more complex designs. For projects that require multi-material combinations or special assembly functions, we can also coordinate related services to simplify production and improve efficiency.

Process	Main Purpose	Advantage	Typical Project
Overmolding	Combine two materials in one part	Better function and appearance	Multi-material products
Insert Molding	Mold plastic around metal inserts	Stronger connection and faster assembly	Electrical or structural components
Micro-molding	Produce very small precision parts	High accuracy for tiny features	Miniature devices and fine parts
Surface Texturing	Improve part appearance and grip	Better aesthetics and usability	Consumer and industrial products

Quality is one of the most important parts of our manufacturing approach. We maintain a controlled workflow with inspection procedures designed to support stable output and consistent part quality across different production stages.

For projects with stricter requirements, we can support inspection, documentation, and compliance-related production needs. Our process is designed to serve customers who need dependable results for international markets and demanding industry applications.

In many cases, injection molding is only one part of the final product. PTMS also supports customers with secondary operations and assembly services so they can receive more complete parts or finished components from one source.

These services help reduce supply chain complexity and improve coordination across the production process. They are especially valuable for projects involving multiple parts, additional finishing steps, or mixed-material assemblies.

Long-term cooperation is often the best proof of a supplier’s reliability. Many of our customers continue working with PTMS because they value our responsiveness, technical support, and practical project management. Our company has worked with PTMS for nearly 10 years. During this time, we completed many projects and were fully satisfied. For each project, we only provided a sketch, and PTMS handled the mold design, mold making, and parts production for us. We visited the company many times and saw how the business grew, which helped us understand why PTMS is such a professional, friendly, and responsive company. A few years ago, when I visited PTMS, I saw a poster in the office that said, “Quality is main target.” It was not just words — it was a real principle, and we can confirm that.

Our company started working with PTMS in 2011. Since the beginning, PTMS has provided professional service and personal attention. Most of our orders involved different parts made of plastic, rubber, aluminum, brass, steel, and other materials. Many of our parts required not only molding, but also second and third operations, which made production more complicated. PTMS always carefully analyzed our part designs before mold making and suggested improvements to avoid possible production problems. We now consider PTMS a highly reliable partner that can achieve very high quality for any kind of part, even for the most difficult designs and strict quality requirements.

What information do you need for a quotation?

To prepare an accurate quotation, we usually need your 2D and 3D file, part quantity, material preference, product application, and any special requirements such as surface finish, tolerance, or assembly needs.

Can you help if I only have a rough idea or sketch?

Yes. Our engineering team can review sketches, concept drawings, or sample parts and help turn them into a manufacturable design.

Do you provide DFM feedback before mold making?

Yes. We can review part structure and offer DFM suggestions to improve manufacturability, reduce risk, and support smoother production.

What file formats do you accept?

We accept STEP, IGES, X_T and SolidWorks files, as well as other common 3D design formats depending on the project.

Can you make both prototype and mass-production parts?

Yes. We support prototype validation, trial production, and large-volume manufacturing according to your project stage.

What is your typical lead time?

Lead time depends on part complexity, mold structure, quantity, and finishing requirements. After reviewing your project, we will provide a clear schedule.

Can you handle secondary operations and assembly?

Yes. We can support post-processing, surface finishing, printing, trimming, and product assembly as part of a complete manufacturing solution.
