Through air Shipment – 7 days

DIE-CASTING PROCESS

In MMTI current Casting item, the smallest was from one of our camera accessories
customer having 11.6mm x 3.0mm size at ZDC2 casting operation.

We use different software – SOLIDWORKS2020, NX12.0 and MAGMASOFT – to simulate and solve the problem. We review the design checklist and procedures that can help minimize or prevent the re-occurrence of the problems. Lastly, we design the repairs needed then proceed to repairing die mold.

Once casting trial is conducted and material specification requirements are met during evaluation then die mold will be transferred to the DMM (Die Mold Maintenance) Group and will be in-charge of maintaining the die mold.

Scraps and NG items are managed through recycling it. They are charged to melting chamber at Furnace machine for a 30% level and been mixed to a 70% raw or virgin material. Right after charging and once melted, cleaning is conducted on molten metal through fluxing activity using a flux chemical. The purpose of that activity is to remove impurities present on the molten metal which might cause NG on product if not remove.

PRODUCTION PROCESS

Tolerance is until ±0.05µ

Without plating requirements it takes 10 days if material is ready With plating requirements it takes 15 days if material is ready. It usually depends on the design of the item, requirement from the customer.

The contract or PO quantity per item is negotiated during price quotation request and PO receiving/confirmation. We offer flexible arrangements with our customers.

Yes, we are committed to deliver good quality products on-time to our customers. During unforeseen circumstances which results to changes in the delivery schedule, we further inform in advance and offer alternative arrangements.

We deliver via air or sea freight depending on customer’s request.
Local shipments via air normally arrives 1-3 days after departure while export air
shipments take 2-4 days.
The sea shipment lead time depends whether it will be shipped via LCL or FCL freight
conditions.
Regardless, we make necessary adjustments with our departure schedule in order to
cater customer’s ETA schedule request.

We are currently serving 37 customers in 10 different countries from Asia, Europe and
North America.

Our standard lead time from PO receiving to delivery is 3 months (although this could
vary due to few factors such as PO volume, customer requests, capacity restrictions,
etc.). The 3-month lead time is inclusive of 2 months material procurement time and 1
month processing time. This standard is communicated to customers so they can
arrange PO and forecast information accordingly in consideration of this information.

PLATING SURFACE TREATMENT

Yes, it is possible

We have available soft etching process to results to anti-reflective anodized finished

Yes, but the colors available are clear, gray and black.

INSPECTION AND QUALITY CONTROL

Defect rate reduction is done in several ways as follows:

  1. When the defect rate is tolerable (that is, within the AQL or the “Acceptable
    Quality Level”), the data is recorded and put under monitoring.
  2. When the defect rate is not tolerable (in this case, it is above the AQL), the
    problem is reported in a “LOT OUT” procedure for the concerned entity to
    investigate the root cause and implement measures.
  3. On a monthly basis, the defect rate data is gathered and analyze with the use of
    the PARETO graph. The top 5 problems are identified. The top five problems are
    then acted upon with measures implemented and monitored for improvement in
    the succeeding months. This is reported in a monthly quality meeting and is
    discussed for further improvement action.

Our measurement process uses different measuring equipment depending on each
specific customer requirements. For common measurement, calipers, micrometers and
different kinds of gauges are used. For dimensions requiring high precision, we are using
the state of the art 3D measuring machine (CMM, Coordinate Measuring Machines),
High Precision/High Magnification Measuring Microscopes, and recently with the latest
CMM with scanning capability.

3D PRINTING

The size of the item that can be printed, the hardness of materials, plastic may vary in
strength capacity and may not be the best for some components.

Prototyping and making of jigs and fixtures.

TOOL MAKING

We are using a CINCOM CG7 Conventional Machine for carbide and compax material, NZX-3 (PCD-PCBN GRINDING MACHINE) for compax material only and Cemented Carbide Tool Grinder for cutting tools.

Based on the machines that we are using right now, we are capable to make brazed
cutting tools which are PCD/COMPAX and CARBIDE material and cutting tools used in a
Lathe Machine.

JIG DESIGN

It depends on the form, size, shape and product specifications. For example, strict
product with complex shape product design would take 6-12 hours to design and simple
product would take 2-3 hours to design.

The material we use in Jig making are JIS A5056 (Aluminum), JIS S45C (Mild Steel), JIS
SKD61 (Steel), Polyoxymethylene (POM), and Bakelite material.

We fabricate our jigs at our Machine Shop area since we are equipped with conventional
machines both lathe and milling, as well as CNC also both lathe and machining centers.

OPTICAL PROCESS

Stereozoom Microscopes (Objective and Ocular Lenses), Factory Automation
Camera, Cinema/Projector, Camera Accessories, Riflescopes, Binoculars, etc.

From 3mm to 66mm Diameter lenses

Through time-to-time checking of chemical concentration, and maintaining proper
temperature and humidity of the area.

Since were using lot of chemicals and other consumables for the processing, it is part of our commitment to keep our environment safe and clean by our water treatment facilities, timely and efficient waste collection by our government accredited third party collectors for the disposal of our solid wastes.

OTHERS

Yes, we have activities in the company like Quality Meetings, CFT Meetings, Trainings, Orientations and Kaizen Activities.

Yes, MMTI have technical support personnel’s who are specialized in different specific
fields and are experts such as Die Mold Maker Engineer and Magma Simulation in-
charge, Die Cast Specialist, Product Engineering Manager, etc. Also, if there are other
concerns or problems that are beyond their skills and capabilities, MMTI have other
technical experts to consult at Japan.
