At Packson, we specialize in manufacturing custom precision mold components and machined parts that meet or exceed international quality standards, including ISO 9001 and 13485. Our team is dedicated to building custom, durable, high-quality precision mold parts with the spirit of craftsmanship.

We take pride in our precision machining process, which is led by engineers with over ten years of experience. This process enables us to provide our customers with more efficient, high-precision, and economical designs and products. We are committed to delivering precision molds that consistently meet or exceed industry-standard tolerances, up to ±0.005mm.To ensure the quality of our products, we use precise equipment for production and manufacture. We follow ISO 9001 and ISO 13485 quality control processes to ensure that every product meets our high standards. Our world-class production and testing equipment, including KEYENCE, Makino, CHARMILLES, Zeiss, and NISSEI, provides a strong guarantee for the precision of your products.

Precision mold parts must meet certain performance requirements to ensure their durability and longevity.

1. Strength and Toughness: Precision molds and tooling components often operate under harsh conditions, which can result in brittle fractures due to large impact loads. Therefore, it is essential for precision molds to have high strength and toughness to prevent sudden breakage during the working process. The toughness of molds and tools depends on factors such as carbon content, grain size, and microstructure of the material.

2. Fatigue Fracture Performance: High-precision injection mold parts often experience fatigue fracture during operation due to the long-term effects of cyclic stress. This can include multiple small energy impacts, tensile, contact, and bending fatigue fractures. This characteristic of custom molding and tooling depends on factors such as strength, toughness, hardness, and content of inclusions in the material.

3. High-Temperature Performance: When the working temperature of precision molds and dies is high, the hardness and strength of the material can be reduced. This can lead to early mold wear or failure due to plastic deformation. Therefore, it is important for the mold material to have high tempering stability to ensure that the mold maintains high hardness and strength at working temperature.

4. Cold and Hot Fatigue Resistance: Some molds are subjected to repeated heating and cooling during the working process, which can cause the cavity surface to be pulled and stressed. This can lead to surface cracking and spalling, increased friction force, and reduced dimensional accuracy. Hot and cold fatigue is one of the main forms of hot working tool failure.

5. Corrosion Resistance: In some cases, molds may be exposed to strong corrosive gases during operation, such as in plastic injection molding. These gases can erode the cavity surface, increase surface roughness, and intensify wear loss effects. This is due to plastic decomposition that produces elements such as chlorine and fluorine that precipitate HCI and HF.

The Components of Precision Moulds
The success of precision mould includes the following:

Precise control of the mold cavity size

Applications of precision moulding and moulds
As mentioned earlier, precision mould is used for the development of various products. But this technology has really revolutionized the development of lenses in various applications because it allows OEM to manufacture cheaper and stronger glass-free lenses. Glass lenses are very delicate, difficult to manufacture, and expensive, but plastic optical lenses have completely changed the optical industry. Precision molding is used for the development and mass production of precision spherical, diffraction, free-form surface, aspheric, and other types of lenses. It is a high-quality product with a perfect optical surface finish.

As a professional precision mould part manufacturer, we provides custom molding services, medical injection moulding, precision mould parts, precision moulds and components, precision mold parts, precision mold components, injection molding china, etc. For more information, please feel free to contact us!

Re: PR kid to local school for P3/P4

❰❰ Quote:

I have 2 kids. We are Singapore PRs. Elder kid is in International School. She will be in P4 next year. Younger kid we are planning to enroll in local school. If I want to register for my elder kid, will it be too much pressure if she starts from P4? I think PSLE preparation already would have started by then. Please provide suggestions if its advisable to register for elder kid to local school?
Also what is the procedure for registering elder kid?

There are many benefits to having both kids in the same system and school calendar. If you are going to do it, now is the time. I know a guy who had a daughter in the Indian international school and moved her to local around P4 as well. She was able to catch up within a year and did just fine on the PSLE. Amazingly, she was even able to transition from Hindi to Tamil within that year, but parents were Tamil speakers.

Re: Which local schools for excellent English/communication skills?

I applaud Addadude on his cool headed response — we can disagree on issues, but personal attacks are not productive.

PR Chance

Hi all,I would like to get some thoughts on my PR chance to maybe ease my concerns :shock:

PR Application Date: Dec2023
PR Status: Pending

Nationality: Malaysian
Race: Chinese
Age: 34
Gender: Female
Degree: Masters (in relations to Psychology), Graduated in the UK
In SG: Since Nov2021
Salary: 42k+
Occupation: Admin Related (Not related to Psychology)
Currently holding Epass.

What are my chances based on the above? Although I do read around that Malaysian Chinese generally have a better chance but I do know someone who just got rejected after 8months. Plus, I know there's nothing to shout about in regards to my salary and work background. I'm just getting anxious cause I'm currently in the process of switching jobs with a rough 15% increment. Nothing in finalised yet with my new employer. I just wish I get my PR before they go through the whole process with the work pass

Re: REP renewal - unique situation

Thanks for the reply - do you know if there is any way to find out if my REP expiry date will automatically be extended when my spouse officially completes the registration as a SGC?

I wasn't sure if I needed to put a request into ICA for this.

1. After your wife become sc, you will remain a PR under her sponsorship, as confirmed by ICA FAQs.
2. As the REP expiry date is available in the ICA portal, so by right you can always check after your wife complete the sc registration. But if you need this info immediately, I think the only way to contact ICA directly?

Re point 1- does that mean that since she is now a SG citizen, my REP will always get renewed as my original PR was under her sponsorship? Or will my REP renewal be based solely on my own merits - e.g. own pay, job .....

Re: Loses money on every property he has bought

The best liquidity is around sought-after schools. Unless the unit (or development) has something very undesirable, you should be able to move it quickly.
