HOW TO SOLVE THE PROBLEM OF SLUG SCRATCHES

Slug Scratches Are A Common Problem In The Production Of Plastic Products, Especially In Areas Such As Automotive Interior Parts That Require High Appearance Quality. The Following Are Some Solutions For Slug Scratches:
1. Check The Mold And Equipment
Mold Positioning And Balance: Check Whether There Is Deviation In The Front And Rear Mold Positioning Of The Mold, Whether There Is Wear In The Fine Positioning, And Whether There Is Sound When The Mold Opening And Closing Guide Pillars. Is The Mold Clamping Unbalanced, And Whether The Clamping Screws Are Insufficient.

Demolding Angle: The Demolding Angle May Be Ok Before Etching, But There May Be Problems After Etching. It Is Necessary To Ask The Etching Manufacturer To Re-Etch, Or To Process It By Sandpaper Polishing.

2. Adjust The Depth And Design Of The Leather Grain
Leather Grain Depth: In The Design Stage, You Should Consider Making The Leather Grain Shallower To Reduce The Risk Of Scratches.

Leather Grain Design: The Grain Surface Is Finer, And It Is Best To Enlarge The Demolding Slope In The Early Stage Of Mold Design.

3. Surface Treatment
Mold Transition Treatment: For The Problem Of Mold Leather Grain Scratches After Biting, You Can Try To Improve It By Doing A Mold Transition Treatment On The Surface.

Reduce The Depth Of Leather Grain: Try To Reduce The Depth Of Leather Grain Without Affecting Customer Requirements. If The Leather Grain Is Corroded Too Deeply, You Can Use Fine Sandpaper To Polish The Leather Grain To Reduce Injection And Holding Pressure, Pressure, And Time.

4. Use Special Materials Or Coatings
Special Treatment: Some Materials With Special Requirements Need Special Treatment, Such As Phosphating, Spraying And Other Methods. This Is To Produce A Thin Film On The Surface Of The Mold To Prevent Or Reduce The Problem Of Strain.

Use Plastic Film: Since The Cost Of Surface Coating Protective Film Is High, Plastic Film Can Be Used Instead. Making A Layer Of Pvc Film Is Also A Good Method.

5. Lubrication And Material Selection
Lubricating Oil: Some Small Products Can Use Lubricating Oil To Solve The Problem Of Strain.

Mold Material And Hardness: Change The Material And Hardness Of The Mold Concave And Convex Mold, Or Titanium Plate And Polish The Product.

6. Process Parameter Adjustment
Injection And Holding Pressure: Reduce Injection And Holding Pressure, Pressure, And Time To Reduce The Possibility Of Strain.

Through The Comprehensive Application Of The Above Methods, The Problem Of Block Leather Grain Strain Can Be Effectively Solved And The Product Quality And Appearance Can Be Improved. It Should Be Noted That The Choice Of Solution Should Be Adjusted According To Specific Product Requirements And Production Conditions.
