Our Infrastructure

• According to our vast experience we have
  established well infrastructural base which is
  associated with highly advance amenities. Our
  infrastructural base is spread into units like
  Quality Assurance, R D, Production,
  Administration, marketing Sales etc. we also
  have an unit for new comer who wants to embark
  new business our unit help them to provide all
  guidance about preferable machineries and
  material and its availabilities we also help them
  to provide short time training session like how
  to operate machine and maintain it
• Mould Making Process
• As a good reputed manufacturer in India, we share
  the basic injection mould making process in our
  company
• EVALUATION
• Product design department provides product
  information to injection mould design
  department, injection mould designers complete
  cost analysis in two working days, and provide
  to R D manager
• R D department release Mould Making Apply to
  plastic injection mould design
• department after confirmed the project.
• Injection mould designers organize relevant
  personnel to review the project base on the
  product information, including product structure,
  mould structure, cooling system runner, slang,
  venting, etc.
• MOULD DESIGN
• After evaluation, injection mould designer begin
  to design the plastic injection mould, including
  3D drawing correction, 3D parting , mould parts
  assembly drawing , EDM Drawing

3

• Electrode Drawing etc., and organize relevant
  personnel to evaluate those drawings , then
  issue to plastic injection mould making
  department.
• MATERIAL ORDER
• Injection mould makers evaluate and study the
  drawings, and order mould materials if there is
  no objection, otherwise communicate with the
  plastic injection mould designers.
• MATERIAL INSPECTION
• Injection mould maker inspect the mould materials
  in time after the material arrive to the
  factory, and arrange technicians to do locksmith
  works, include turning , grinding, milling ,
  screw holes, water carrying hole, center hole,
• VMC WORK
• After material inspection next step would be VMC
  machining we have high precision VMC Machines.
  The technician pay attention to the precision of
  each right angle sides, avoid empty of the
  center hole and each production base.

PRE TRIAL PROCESS 8. In tryout, injection mold
designers ,plastic mould makers and other
personnel should go to the site , making
analysis and solution of abnormal in tryout, and
fill mold Tryout Report While tryout cycle
time the products are defect-free Our creative
team is pay attention to minimize all common
molding defects as as below
Keep these factors in mind when designing your
injection moulded part, and remember that it is
easier to avoid problems in the beginning than
change your design down the line.
Molding Defects Alternative Name Descriptions Causes
Blister Blistering Raised or layered zone on surface of the Plastic part Tool or material is too hot, often caused by a lack of cooling around the tool or a faulty heater
Burn marks Air Burn/Gas Burn Black or brown burnt areas on the plastic part located at furthest points from gate Tool lacks venting, injection speed is too high
4
Color streaks (US) Localized change of color Plastic material and colorant isn't mixing properly, or the material has run out and it's starting to come through as natural only
Delamination Thin mica like layers formed in part wall Contamination of the material e.g. PP mixed with ABS, very dangerous if the part is being used for a safety critical application as the material has very little strength when delaminated as the materials cannot bond
Flash Burrs Excess material in thin layer exceeding normal part geometry Tool damage, too much injection speed/material injected and clamping force too low. Can also be caused by dirt and contaminants around tooling surfaces.
Embedded contaminates Embedded particulates Foreign particle (burnt material or other) embedded in the part Particles on the tool surface, contaminated material or foreign debris in the barrel, or too much shear heat burning the material prior to injection
Flow marks Flow lines Directionally "off tone" wavy lines or patterns Injection speeds too slow (the plastic has cooled down too much during injection, injection speeds must be set as fast as you can get away with at all times)
Jetting Deformed part by turbulent flow of material Poor tool design, gate position or runner. Injection speed set too high.
Polymer degradation polymer breakdown from oxidation, etc. Excess water in the granules, excessive temperatures in barrel
Sink marks Localized depression (In thicker zones) Holding time/pressure too low, cooling time too short, with sprueless hot runners this can also be caused by the gate temperature being set too high
Short shot Non-Fill/Short Mold Partial part Lack of material, injection speed or pressure too low
Splay marks Splash Mark/Silver Streaks Circular pattern around gate caused by hot gas Moisture in the material, usually when resins are dried improperly
Stringiness Stringing String like remain from previous shot transfer in new shot Nozzle temperature too high. Gate hasn't frozen off
Voids Empty space within part (Air pocket) Lack of holding pressure (holding pressure is used to pack out the part during the holding time). Also mold may be out of registration (when the two halves don't centre properly and part walls are not the same thickness).
Weld line Knit Line/Meld Line Discoloured line where two flow fronts meet Mold/material temperatures set too low (the material is cold when they meet, so they don't bond)
Warping Twisting Part Distorted part Cooling is too short, material is too hot, lack of cooling around the tool, incorrect water temperatures (the parts bow inwards towards the hot side of the tool)
