Information
We develop and produce custom PPSU sterile dilators, precision‑machined surgical instruments built to meet strict dimensional tolerance, surface smoothness and biocompatibility demands for hospital operating rooms, outpatient clinics and CSSD sterile supply departments. These high‑strength polymer tools serve as a practical alternative to conventional metal instruments and single‑use plastic disposables, supporting safe dilation work in multiple minimally‑invasive clinical scenarios.

Product Details
PPSU sterile dilators are widely used across different clinical departments. Made from unmodified medical‑grade polyphenylsulfone raw resin, these custom‑built instruments can go through repeated sterilization cycles without obvious performance decay. Many ordinary plastic dilators will develop micro‑cracks or release trace chemical substances after frequent high‑temperature sterilization; PPSU material avoids such risks and supports long‑term repeated clinical use.
For gynecological outpatient work, we make tapered‑tip PPSU dilators for progressive dilation during routine examinations and minor surgeries. Tips are fine polished to reduce tissue irritation during operation. We can supply sets with multiple diameter specifications to match real‑world clinical step‑wise dilation protocols.
In minimally‑invasive surgical settings, custom sized dilators help create stable working access channels. Compared with metal counterparts, the lighter weight helps relieve hand fatigue for surgeons, and finely finished surfaces reduce friction during insertion and removal.
We also make variant PPSU dilators for ENT examinations and orthopedic puncture access tasks. The material holds up well against repeated wiping with common hospital disinfectants, with little risk of discoloration or surface brittleness.
For CSSD departments, these dilators fit mainstream hospital sterilization workflows, including steam autoclave and ETO gas sterilization. Each finished unit is built to withstand continuous cycles of cleaning, disinfection and sterilization for daily hospital use.
Core Features
Medical‑grade biological safety
We only adopt virgin PPSU raw material, no recycled fillers or harmful additives are mixed in. The material is BPA‑free and will not release irritant substances that may come into contact with human tissue. All material selections follow ISO 10993 requirements for surgical devices with body contact.
Real‑world multi‑sterilization durability
Our PPSU dilators can sustain repeated 121 °C and 134 °C autoclave processing. After hundreds of sterilization cycles, products still keep stable dimensions and smooth surfaces. Unlike PC materials, PPSU shows strong resistance to hydrolysis under long‑term high‑temperature humid conditions.
Flexible custom manufacturing with tight tolerance
We adjust outer diameter, tip taper angle, surface polishing standard and anti‑slip handle structure according to customer drawings or physical samples. We combine injection molding and manual fine post‑polishing to remove burrs, which is critical for surgical instruments that touch human tissue.
High‑toughness and lightweight physical property
PPSU delivers good fracture resistance. Compared with traditional metal dilators, polymer‑made instruments cut down overall weight. This brings less hand burden for clinical staff, and will not form sharp fragments even if the instrument is accidentally dropped.
Stable quality from batch to batch
Molding, surface finishing and final inspection are all completed in dust‑controlled workshops. For each production lot, we carry out raw material verification, dimensional measurement and simulated sterilization aging test. Products are suitable for bulk purchasing from hospital groups and medical device OEM customers.

FAQ
What manufacturing services does DASHCONN provide?
+
-
We handle the full custom manufacturing process for PPSU sterile dilators, from rapid prototyping and sample trial production to large‑scale mass production. Our English‑speaking project team assists with technical confirmation, design adjustment, production progress follow‑up, logistics arrangement and after‑sales support. Overseas customers are welcome to visit our production site and testing lab.
What file types do you accept for quoting?
-
We support common 3D formats for technical evaluation and quotation: STEP, STP, STL, PRT and X_T. You may upload design files on our platform to get fast feedback on cost. If you only have physical samples instead of drawings, we also provide reverse‑engineering services.
Is custom PPSU injection molding suitable for small‑batch prototyping?
-
Injection molding is one feasible option for PPSU dilator prototypes. For trial orders under 10 pieces, our engineers will review instrument structure, material limits and your project budget. We will advise whether precision CNC machining or small‑batch mold opening is more cost‑effective for your timeline and budget.
What shipping methods do you offer?
-
Global shipments can be arranged via DHL express. Customers may also utilize their own courier accounts or appointed freight forwarders to satisfy personalized logistics arrangements.
What payment terms do you accept?
-
Bank transfer serves as our primary accepted payment method for all custom production orders.
