  Tips on Budgeting for a Domestic Helper

  

  1. Calculate Total Monthly Expenses

  

  When budgeting for a domestic helper, it¨s essential to calculate the total monthly expenses. Include the helper¨s salary, monthly levy, food, accommodation, and any other recurring costs. This will give you a clear picture of the monthly financial commitment.

  

  For example, if you hire an Indonesian helper with a salary of SGD 600 and qualify for the concessionary levy of SGD 60, your monthly expenses might look like this:

  

  Salary: SGD 600

  

  Levy: SGD 60

  

  Food: SGD 250

  

  Accommodation: SGD 100 (if providing a private room incurs additional utility costs)

  

  Medical Insurance: SGD 25 (annual cost divided by 12)

  

  Total Monthly Expense: SGD 1,035

  

  2. Plan for One-Time Costs

  

  Factor in one-time costs such as agency fees, initial medical examinations, and the Settling-In Programme. These expenses can add up, so it¨s important to plan for them in advance.

  

  For example:

  

  Agency Fees: SGD 2,000

  

  Initial Medical Examination: SGD 100

  

  Settling-In Programme: SGD 75

  

  Total One-Time Cost: SGD 2,175

  

  3. Set Aside an Emergency Fund

  

  It¨s wise to set aside an emergency fund to cover unexpected expenses, such as medical emergencies or early termination of the helper¨s contract. This fund can provide financial security and peace of mind.

  

  Consider setting aside a few months’ worth of the total monthly expense as an emergency fund. For instance, having an emergency fund of SGD 3,000 can cover approximately three months of expenses.

  

  4. Consider Concessionary Levy Eligibility

  Bubbles, or air traps, occur when air gets trapped in the mold cavity, leading to voids or bubbles within the part. These can weaken the part and affect its appearance.

  

  Prevention Tips:

  

  Mold Venting: Ensure proper venting in the mold to allow trapped air to escape. Venting can be achieved through the use of vents, runners, and gates.

  

  Injection Speed: Adjust the injection speed to allow air to escape before the material fills the cavity. Slower injection speeds often help in reducing air traps.

  

  Material Drying: Thoroughly dry hygroscopic materials before molding to prevent moisture from causing bubbles.

  

  Gate Design: Optimize gate design and placement to ensure smooth flow and minimize turbulence that can trap air.

  

  4. Flash

  

  Flash is the excess plastic that seeps out of the mold cavity and solidifies, creating unwanted thin layers or protrusions along the parting lines.

  

  Prevention Tips:

  

  Clamp Force: Ensure sufficient clamping force to keep the mold halves tightly closed during injection.

  

  Mold Maintenance: Regularly inspect and maintain mold surfaces to ensure they are clean and free of damage or wear.

  

  Process Parameters: Optimize injection pressure and speed to prevent material from forcing its way out of the mold cavity.

  

  Mold Design: Incorporate precise parting line tolerances and properly align mold components.

  People who like to swim or dive with their watches usually have a waterproof performance test for their watches once a year in order to feel at ease. This test can only be carried out after the relevant parts of the watch are updated, such as battery replacement and maintenance.

  

  All excellent watchmakers have professional instruments, which can carry out stress tests for watches at a reasonable depth (that is, the depth often visited by swimmers and divers). This instrument will not exert strong pressure on the cover. If it is found that the watch is not completely encrypted, it will not let other foreign objects soak in the watch. This test can only be carried out in a vacuum environment. Once the sensor placed on the surface detects any slight deviation, it will show that air is leaking from the watch case through the cover. If you can pass the test that lasts for several minutes, the watch will be waterproof.

  

  In order to ensure that watches can cope with the great pressure faced by professional divers when working in the deep sea, watches must be tested by more stringent testing tools. This kind of test is risky, because once it is poorly sealed, water will enter the meter. Moreover, this test is more time-consuming than vacuum pressurization test. The method is to put the watch into the water injection instrument and then pressurize it. When the pressure is released, heat the watch and place a drop of water on the watch mirror. If water vapor condenses on the inside of the watch mirror, it means that the waterproof apron is leaking and new waterproof accessories must be replaced.

  

  In the daily movement maintenance, every watch must pass the air pressure test, and some authorized service centers will add the real water test. You can use a watch that has passed both the air pressure test and the real water test with confidence.

  3. Hemostasis: It is necessary to stop bleeding in time after operation, when the muscle and periosteum are separated, and bone wax should be applied to the wound after bone removal.

  

  4. Debridement: The bone components appearing during the operation need to be cleaned with saline, and the powder of these components will grow together with the bone on the wound surface of the incision.

  

  5. Adjustment: There will be changes in masticatory muscles and bones after operation, which need to be treated according to the masticatory hypertrophy of beauty seekers. If it is too hypertrophy, some muscles can be removed from the back.
