Custom S136 Mold Plates | High-Precision EDM Machined Injection Tooling

Product Overview

Senlan Precision manufactures non-standard injection mold plates made from S136 stainless mould steel, produced strictly to customer drawings (Built-to-Print). By combining CNC machining with EDM processes, these mold plates achieve high dimensional accuracy, stable flatness, and reliable structural integrity. They are designed for precision plastic injection moulds used in packaging and medical applications where corrosion resistance and repeatable performance are required.

Key Features & Advantages

• Material: S136 stainless mould steel with good corrosion resistance and polishability

• Non-standard manufacturing: Fully customized dimensions and structures per drawings

• EDM processing: Accurate formation of complex cavities, slots, and sharp internal features

• High precision: Tight control of flatness, parallelism, and positional tolerances

• Process stability: Suitable for multi-cavity and high-cycle mould systems

• Built-to-Print: OEM manufacturing without design assumptions or standardization

Applications / Industry Use

• Bottle and container mould bases

• Cap and closure injection moulds

• Medical plastic mould tooling

• Precision packaging mould systems requiring corrosion resistance

Mold Structure & Design Description

The injection mold plate functions as a core structural component of the mould assembly, supporting cavity inserts, core systems, cooling channels, and guiding elements. EDM processing is applied to areas with complex geometry or tight internal corners that cannot be achieved by conventional machining. All interfaces, mounting features, and tolerances are manufactured according to customer-supplied drawings to ensure compatibility with existing mould assemblies.

Manufacturing Capability & CNC Machining

• Machining equipment: High-precision CNC machining centers from MAKINO (Japan) and HARDINGE (USA)

• Processes: CNC milling, CNC drilling, wire EDM, sinker EDM, surface grinding

• Accuracy: Machining tolerance up to ±0.002 mm, depending on design requirements

• Surface condition: As-machined, EDM finish, or further grinding/polishing as specified

• Inspection: Flatness, parallelism, hole position, and interface dimensions verified before delivery

Custom Development / OEM Workflow

1. Drawing & specification review – Technical feasibility and tolerance assessment

2. Material confirmation – S136 grade selection and heat treatment condition

3. Process planning – CNC + EDM machining sequence definition

4. Manufacturing – Precision machining with in-process inspection

5. Final inspection & delivery – Dimensional verification and export-ready packaging

Quality Control & Export Experience

• Incoming material verification and traceability

• In-process dimensional checks at key machining stages

• Final inspection reports available upon request

• Experience supplying mould plates and components to overseas mould manufacturers and processors

FAQ (Technical & Purchasing)

Q1: Can the mold plate be supplied fully hardened?
Yes. Heat treatment conditions can be specified according to the drawing or application needs.

Q2: Is EDM mandatory for all plates?
No. EDM is applied only where required by geometry or tolerance; CNC machining is used wherever feasible.

Q3: Do you manufacture complete moulds?
Yes. In addition to mold plates, Senlan Precision supports complete mould and multi-cavity mould manufacturing.

Q4: Can small batches or single pieces be produced?
Yes. Prototype, low-volume, and serial production are all supported.
