Design standard Custom Medical plastic injection mold material selection principles:
The first point: the selection of materials must meet its use function in the mold;
The second point: Under the premise of meeting the first point, consider the cost factor and the mold type to select the appropriate material.
The following are Custom Medical plastic injection mold that standardized on different mold parts and deal with different precision requirements.
Custom Medical plastic injection mold using is mainly divided into four parts: Moldbase, Insert bolck, Insert , Slide Component
Moldbase:
(1). Cavity plate & core plate
Common materials: P20, 618HH, 718HH
Use hardness: N/A;
When the precision of the template is very high due to product factors, it can be used: M310, RAMAX, using hardness: N/A
(2). Core back plate & ejector back plate
Common materials: P20,
Use hardness: N/A;
Use when there are certain performance requirements: 618HH, 718HH,
Use hardness: N/A.
(3). Top & bottom insulation plate

Use hardness: N/A;
(4). Other templates except (1) (2) & (3), such as Top & bottom insulation plate, Ejector plate, support bolck, etc.
Common material: S50C, use hardness: N/A;
Use when there are certain performance requirements: P20, use hardness: N/A.
Insert block:
(1). Insert block.
Common materials: 1.2083,
Use hardness: 52-54HRC;
When the performance requirements are high, it can be used: M310, STAVAX,

(2). Insert Back Plate
Common materials: 1.2083,
Use hardness: 52-54HRC;
Can be used when performance requirements are not high: 8402
Use hardness: 50-52HRC.
Insert :
(1). Insert Participate in product forming.
Common materials for common requirements: CALMAX,
Use hardness: 54-56HRC;
The workpiece is a slender type that is expected to be easily broken in production or has an Insert designed for insertion.
Commonly used: VIKING, W360,
Use Hardness: 56-58HRC,
For higher requirements or use: K390,
Use hardness: 60-62HRC
(2). Insert that does not participate in product molding.
Common materials: 8402
Use hardness: 50-52HRC;
Component:
(1). Mould Component
1) LocatIon Ring
Commonly used: S50C,
Use hardness: N/A;
2) Sprue Bush
Commonly used: SKD61,
Use hardness: 48-52HRC;
3) Support Pillar
Commonly used: S50C, 618,
Use hardness: N/A;
4) Stopper
Commonly used: S50C,
Use hardness: N/A;
(2). Slide Component
1) Slide Cam Hold
Commonly used: XW-10,
Use hardness: 58-60HRC;
2)Angle Cam
Commonly used: XW-10 (56-58HRC), or use: 8402 (50-52HRC);
3) Guide Rall & center Guide
Commonly used: XW-10 (56-58HRC), or use: 8402 (50-52HRC);
4) Pressure Pad
Commonly used: XW-10 (56-58HRC), or use: 8402 (50-52RC);
5) Wear Plate
Commonly used: XW-10 (56-58HRC), or use: 8402 (50-52HRC);
6) Cover Plate
Commonly used: 8402 (50-52HRC);
Material usage principle: parts that have a moving relationship with each other must use different materials;
If the same material is required, reduce the consumable replacement parts by 2HRC.
